Maintain quality while reducing Photoshop file size

Designer's skepticism

Transforming photographs is a mandatory procedure for a designer and retoucher, but in pursuit of the quality of the final result, we often forget about the little things where the devil lies. So we spoil the porridge with and without oil, even at the beginning of work, ignoring the details.

This article will tell you how, by following some postulates, I achieve better picture quality without doing a lot of extra work on it.

Experimental painting from Thomas Le Corre, view the project on Behance

The principle of calculation of transformation

Let's figure out how the transformation calculation works:
By reducing the image, the program takes the nearest pixels and merging them produces an average color for the newly created one, and when enlarging, information, on the contrary, is taken from neighboring pixels to create new ones. Rough recalculation will at best preserve the image quality if the scaling was insignificant (for example, ±10%)

The difference between the original and scaling an illustration and then restoring the size.

With any transformation, the original quality of the illustration is lost. It doesn’t matter whether the picture was scaled, distorted or rotated. The principle “More manipulations - worse results” applies.

What to avoid

In scaling

We avoid “incorrect” size values.
We “read” the sizes by percentage. Correct sizes are considered to be all those that are divisible by 5 or, at worst, 2. The top is headed by: 25, 50 and 75%;
They are followed by: 10 and 90%, 20 and 80%, 40 and 60%.
Then everything that is a multiple of 5, but not previously announced, closes the list of successful ones - multiples of 2.

The scale will be calculated more correctly if the picture is reduced not to 73.91%, but to the normal 75%.
If the size is needed exactly with the figure above, and not rounded by us to 75%, I will condescend to round as much as 73%. It must be remembered that there is no concept of “half a pixel”. There is a pixel - this is the smallest unit. Anything smaller is also a pixel, but with transparency, the density of which is calculated based on the size of the “under-pixel”.

In a turn

I avoid several rotations when I can get by with one: Instead of two at 15°, I do one at 30°.
The exception is turns that are multiples of 90°. The pixel does not undergo recalculation, since it remains the same, changing its location.

Turns that are multiples of 45° are killer. They crush the pixels the most and we get garbage.

Poor quality is visible to the naked eye. The illustration is rotated 8 times by 45° (made a 360° rotation)

Complex manipulations

The program does not allow correct rendering during complex transformations and therefore operations must be carried out step by step.
The result when scaling and rotating at the same time will be worse than if the object were first rotated and then scaled. Moreover, the difference in quality is noticeable even to an inexperienced user.

Note the “waves” and “ladders” at the edge of the monitor, the black button, the edge of the image and the bend line of the laptop, which appeared from inconsistent transformation (Reducing the scale to 68% and rotating by 27°)

We scale correctly

Transformation in live mode is much worse than the final one, when the program allows you to change the size in a dialog box while saving the result on your computer.

For simple, single scaling, the Save as button is sufficient. or Save for web with a drop-down dialog box in which you can specify the file format and its required dimensions.

It is in the save dialog that it is recommended to set the final dimensions to save the layout. Dimensions can also be set as percentages.

And then we insert our image into the layout and place it in the right place.
It takes an extra 15 seconds, and the result is of the highest acceptable quality.

The best sequence of all types of transformations

Finally, I will describe the most successful sequence of actions that preserves the quality in the best condition.

When decreasing

First of all, distortion is always done, followed by rotation. And only after that we reduce the object.

This is due to anti-aliasing, which occurs by merging pixels when reduced. The reduction itself is best done through the previously described pop-up save window.

When increasing

Priority should be given to scaling, after which you can act as you wish - as it is more convenient.

How to reduce the size of any image in Photoshop in two ways?

Good day to you, my dear friends. This is a situation I often encounter. For example, I want to put an avatar on some website, I cut out the desired area of ​​my photo or other picture, and save it. And when I go to the site, it turns out that it accepts photos for avatars no larger than 150*150 pixels and 100 kilobytes, for example.

I look at my photo, and it is 1920*1200 in size and weighs more than a megabyte. Naturally, this site will not upload such a photo. So what to do? Well, in general, this is why we gathered here.

In today's tutorial I'll show you how to reduce the size of an image in Photoshop to fit your needs. Moreover, the matter will affect both the size of pixels and the size of kilobytes (well, or megabytes), and the quality will not even suffer. Just do not confuse reducing the size of a picture with a regular change in scale, since here we will actually reduce the picture, and not create an appearance. Let's take this picture today.

Easy saving

1. First, load the image into Photoshop.
2. Now go to the main menu and select “Image”, and in the drop-down list that opens “Image size”.

In the window that opens, you can see two cells (width and height) with the current size of the picture. This is where you have to change the size itself.

By default, width and height are linked in this way. This means the size is proportional. That is, if you change the value in any of these two cells, the size in the second cell will automatically change. Those. the image proportions will be preserved.

And if you click on this chain, the connection will be broken and changing any value will not lead to a change in another value. The picture will become disproportionate.

Just like when you create a new document in Photoshop, you can choose units of measurement, such as pixels, centimeters, inches, or even percentages of the current image.

After resizing, at the top of this window you will see the current size of the image in kilobytes (or other units), and the old size in brackets. This is not the final size, so don't pay too much attention to it.

Well, is the point clear? Let's look at a live example for greater clarity.

I need a photo for a website measuring 200*200 pixels. I take our photo size 1920*1200 and load it into Photoshop. And then point by point.

1. Select the “Frame” tool, setting the proportion to square (1 to 1) and select part of the photo so that the entire face and a small part of the body up to the chest are included in the frame. And we frame it. We will get a square image, but the size is clearly not 200*200. Therefore, let's proceed directly to the reduction.
2. We go to the “Size” of the image, as I described above, and set the width there to 200 , and the height will be set by itself, since there is a connection. I check that the unit of measurement is “pixels” and click OK . That's all. Now all that remains is to save the image, but you should already know that.

Saving for WEB

If you need the image to upload it to the site, and not to keep it as a memorable photo, then you can save it in a slightly different way. With this method, the size of the picture (that is, its weight) will decrease several times more, and you will not notice any loss of quality.

So, we again have an unlabeled image with a higher resolution. If you need to crop, then crop, but then you must click “File”, then “Export”, and in the next drop select “Save for web (old version)”.

ATTENTION! This path is valid for Photoshop version 2015. For earlier versions, you simply go to the "File" menu and select "Save for Web". There will be no “Export” item there.

In the window that opens, select “High quality JPG” and you don’t have to set the quality to more than 60 . If you set it more, you won’t notice the difference, but the picture will take up more space, although not very significantly.

Below you will see the line “Image size”. The essence is absolutely the same as in the previous example. You need to reduce the size in width and height. There is even a chain). We set it to 200*200, and then click “Save”. Voila)

As a result, using the above two methods, I received two images measuring 200*200 pixels. But the size (volume) of the first image is 26 kilobytes, and the second one is 10. Accordingly, the second one is more convenient to use, but only if you save for websites. For regular storage of a reduced copy, it is better to use the first method.

By the way, you can also enlarge images and photographs. To do this, drive new dimensions into the cells in the same way. But I wouldn’t advise you, since the loss in quality is noticeable. Of course, it is possible to do this without loss of quality, but it is much more difficult.

Well, here are some good tools for reducing the size of photos and other images. After all, nothing is complicated, right? By the way, for a deeper study of Photoshop, I suggest you familiarize yourself with the wonderful course on Photoshop for beginners. Lessons in video format are very well received and are more convenient for learning the program. All lessons are told in human language, unlike many other similar courses. I recently decided to watch this course and learned a lot of new and interesting things. so don't get lost.

Well, on this cheerful note I end my lesson today. Train, practice, and most importantly, don’t forget to subscribe to my blog updates if you want to keep abreast of all the most interesting things. Good luck to you and bye bye!

Image size and resolution

On this page

Photoshop has updated the Image Size dialog box. For more information, see Resize an image.

About pixel dimensions and resolution of printed images

Pixel dimensions change the total number of pixels across the width and length of the image. Resolution is a measure of the clarity of detail in a raster image and is measured in pixels per inch (ppi). The more pixels per inch, the higher the resolution. In general, a higher resolution image results in a higher quality print.

If resampled (see Resampling), the amount of image data remains the same when the print size or resolution changes. For example, when you change a file's resolution, its height and width are changed so that the amount of image data remains the same.

Photoshop lets you see the relationship between image size and resolution in the Image Size dialog box (Image > Image Size). Clear the Interpolation option as there is no need to change the amount of image data. Then change the width, height or resolution. When one of the values ​​changes, the others will be brought into line with the first. When Image Resampling is selected, you can change the resolution, width, and height of the image to suit your printing or display needs.

Quickly display the current image size

If you need to quickly display the current dimensions of a document image, use the help window at the bottom of the document window.

file size

The image file size is the physical size of the file in which the image is stored. It is measured in kilobytes (KB), megabytes (MB), or gigabytes (GB). The file size is proportional to the pixel dimensions of the image. The higher the number of pixels, the more detailed the image obtained when printed. However, storing them requires more disk space and slows down editing and printing. Thus, when choosing a resolution, a compromise must be made between image quality (which must contain all the necessary data) and file size.

Another factor that affects file size is its format. Due to differences in compression methods used in the GIF, JPEG, PNG, and TIFF file formats, file sizes with the same pixel dimensions can vary greatly. The bit depth of the color and the number of layers and channels also affect the file size.

Photoshop supports maximum image pixel dimensions of 300,000 horizontal and vertical. This limitation determines the maximum permissible size and resolution of the image on the screen and when printing.

About your monitor resolution

Monitor resolution is described in dimensions (in pixels). For example, if the monitor resolution and the pixel dimensions of the photo are the same, then when viewed at 100% scale, the photo will occupy the entire screen. The size of the image on the screen depends on a combination of factors - the pixel size of the image, the size of the monitor and the resolution of the monitor. Photoshop allows you to change the visible size of an image on the screen, so the user can easily process images of any size.

When preparing images for viewing on the screen, you should use a monitor with the lowest possible resolution.

Printer Resolution Information

Printer resolution is measured in dots per inch, dpi. Generally, the more dots per inch, the better the quality of the printed image. Most inkjet printers have a resolution of 720 to 2880 dpi. (Technically speaking, unlike photo output devices and laser printers, inkjet printers leave microscopic blots.)

Printer resolution is different from, but related to, image resolution. To print a high-quality photograph on an inkjet printer, the image resolution must be at least 220 ppi.

Screen lineage is the number of dots or halftone cells per inch that are output when printing images in grayscale or color separation mode. Screen lineature (also called screen frequency ) is measured in lines per inch (lpi), that is, lines of cells per inch in a halftone screen. The higher the resolution of the output device, the higher (fine) the apparent frequency of the raster.

The relationship between image resolution and screen lineature determines the quality of detail in the printed image. To obtain the highest quality halftone image, an image whose resolution is one and a half or even two times greater than the screen lineature is usually used. But for some images and output devices, lower resolutions can produce good results. To determine your printer's screen size, you must consult your printer's documentation or your service provider.

Some 600 dpi photo output devices and laser printers use screen technologies other than half-toning. If you are printing an image from such a device, check with your service provider or printer documentation for guidance on selecting the image resolution.

Determining the optimal image resolution

If you plan to print an image using a halftone screen, the range of suitable image resolutions depends on the screen lineage of the output device. Photoshop can determine the recommended image resolution based on the raster lineage of the output device.

If the image resolution is more than 2.5 times the raster frequency, a warning message will appear when you try to print the image. This means that the image resolution is higher than what is required for printing on this printer. Save a copy of the file and then lower the resolution.

Effectively reduce image size without losing quality

This is another material on working with images.

In it you will learn how to reduce the size of an image without losing quality using Paint, Photoshop and an online service.

Moreover, you will learn how to do this in two aspects. After all, image size has 2 meanings:

• Size in pixels, that is, the height and width of the image;
• Size in kilobytes, that is, the weight of the image on a computer or other media.

This material is suitable for anyone who is interested in reducing the size of their images, photographs, and so on. And it will be very useful for website owners, since it is strictly not recommended to place large-sized and weighty pictures in your materials.

Let's start with a little consideration of the need for all the actions discussed below.

Regarding changing the height and width of the image, there are many options: you need the required size for printing, for posting on the site, to reduce the same weight of the image, since it decreases when the size is reduced.

Weight reduction may be required to save weight on storage media (hard drive, flash drive, etc.), to quickly load images on a website, and so on.

There are actually a huge number of options. In order not to languish, we begin to practice.

By tradition, I give a detailed video lesson in which I showed everything clearly.

Now for lovers of text instructions.

Resizing in Paint

To change the height and width dimensions, I do not recommend using any online services, since this can be done using a standard set of programs and even the standard editor of the Windows operating system - Paint.

Open the image in Paint and on the “Home” tab there is a “Resize” item.

By clicking on it, we can change the size without losing quality (if we reduce it) and without losing proportions. To do this, be sure to activate the setting to maintain proportions.

By changing the horizontal and vertical size parameters, you adjust the width and height of the image accordingly. Select the necessary parameters, click on the “Ok” button, and then save the final file to your computer.

We're done resizing the image in Paint.

By the way, changing the width and height parameters also affects the weight of the image. Therefore, take note of this.

Now let's look at the option using Photoshop.

Resizing in Photoshop

Open our image in the program and move to the “Image - Image Size” item.

In the next window, the change occurs in the same way as in Paint. Make sure the checkbox is checked to maintain proportions and set the required height or width parameters.

After clicking the “Ok” button, the size parameters will be applied and you can save the file.

These methods are quite sufficient to resize the height and width of images.

Now we will look at 2 ways to reduce the weight of images.

But before that, I want to note that you already know one way. If you do not need images of extremely large sizes, then you can reduce their height and width, thereby reducing the weight by several, or even tens of times.

Reducing Weight in Photoshop

This method will be very useful for website owners, since the smaller the page weighs, the faster it loads. And this is very important. The method is also suitable for any needs.

After opening an image in Photoshop, you need to immediately save it, but not usually, but for the web and devices.

In the next window you need to set image quality parameters:

• Quality - high (60-70). Adjust the value to suit your needs;
• Format - jpeg. If you need to save transparent areas in the image, then you need the png format;
• We also set the “Progressive” setting.

You can also change the sizes directly in this window, and not separately through the “Image - image size” item, as I showed in the paragraph earlier. It is very comfortable.

After setting the parameters, save the settings (see screenshot above).

This is the only way I was able to reduce the weight of the image from 116 kb to 75 kb without changing the dimensions (height and width remained the same).

In this method, you can play with the quality value. It all depends on why you need to reduce the weight of the image. It is quite possible that you can set the parameter lower, making the weight even less.

Now let's look at how to reduce weight using an online service.

Online service for optimization

This method is very useful for reduced images. For example, if I have already reduced the image earlier in Photoshop, then using the service we can finalize the size.

The service is called krakin.io. Let's move on to it. I provided a link directly to the image selection page.

On this page, you first need to decide on the degree of image compression. There are 2 parameters responsible for this:

• Lossy — strong compression (set by default);
• Lossless - less compression.

You can determine this parameter only by testing them. Therefore, try to compress the image this way and that, and then select the desired option.

Then you can upload an image, which is immediately optimized without your participation. To do this, click on the file selection area from your computer.

The image is immediately optimized and we will see a report on the work done under the area for selecting a file.

It can be seen that the original file size was 77 kb, and after optimization it became 59 kb. It also shows how much was compressed in kilobytes (18 kb) and as a percentage (23.8%).

To save the compressed image, you must click on the “Download this file” button in the last “Status” column. We will be transferred to a new tab where the final image will open so that we can evaluate it. To save, you need to right-click on the image and select “Save image as.”

Next, according to the standard, select the save location and write a name for the file.

If you watched the video at the beginning of the article, where I clearly showed the process and all the nuances of this article, then you know that only these methods can reduce an image from 360 kb to 40 kb. And this is not the limit.

This material has come to an end. As an ordinary Internet user, you will be able to use all the methods described in the article.

In the comments below, I would be interested to know some of your ways to reduce the weight of pictures. Maybe there is something simpler but more effective. Therefore, I’m waiting for you below near the comment form.

Compress images in Photoshop without losing quality

Hello. Every day I process dozens of images, which I then add to my blog. Some files “weigh” a lot, but it is not recommended to place such elements on the site, since the page loading time increases. I suggest you familiarize yourself with a simple method on how to compress a photo in Photoshop.

Why Photoshop?

Probably, such a question could arise in your head. I agree, there are other applications and even online services that allow you to compress images. But this is a topic for my subsequent publications! And today I want to talk specifically about working with this program, since some of my readers ask about it.

Where to begin?

Most likely, the required graphic editor is already installed on your computer, and I will not talk about the downloading and installation process.

If you have a lot of photos, I recommend organizing them into folders according to topic. Then it will be easier for you to navigate what is saved and where. Otherwise, confusion may occur.

Pay attention to the format. If you saved edited objects from the Internet or copied them from a camera, then most often they will have the extension “jpeg/jpg”. But it could also be “gif” or “png”. The latter type is characterized by a transparent background, which makes such images unique. If you want to retain these properties during compression, then it is better to place such objects in a separate location (folder). Next you will find out why.

The process has begun!

Let's move on to the instructions on how to compress a photo without losing quality in Photoshop. It's very simple!

• Launch the Adobe Photoshop editor. It is better to use the latest version, although the functionality described below is present even in “old” editions of the software.
• Open the desired processing object (or several) using the corresponding item in the “File” menu or simply press Ctrl + O on the keyboard:

It is worth noting that initially the source took up 442 KB of disk space!

• Now go to “File” again and click on the “Save for Web” option. ":

• A new window will open with many settings. But don't panic, we'll figure it out now. On the top right, you can select a save format from the drop-down list (jpeg by default) and specify the quality from 0 to 100 using the “slider”. It is possible to specify preset compression settings: minimum, medium, etc.

• Below the preview area you can see the new size of the element. In this case, it was reduced to 232 KB. But this is not the limit. You can change the quality (reduce) until you begin to notice digital artifacts - uneven edges, waves, cubes. Also, you have the right to change the resolution of the element by specifying a different width and height. Perhaps you don't need such a big "lion". This will further minimize weight.

Now you know how to compress the size of a photo in Photoshop. But let me tell you a little about the features of the “png” format.

Instructions for PNG

• Let's say you saved the source, which is placed on a transparent background.

• If you try to save it using the above method, the background will be filled with solid white:

• You need to change the type from above to PNG-8 or PNG-24:

• If the first option (8) is selected, then a little to the right you will be able to select the number of colors (from 2 to 256). You can try changing these values ​​and look at the image. It is worth noting that this solution is optimal if your source is not too saturated and varied in terms of color, and you are not particularly concerned about the evenness of the edges.
• For better quality, you should choose mode 24, which does not have any special settings. Yes, and you won’t be able to compress it too much. Therefore, it is better to play a little with PNG-8.

I suggest watching the following video, which will show in more detail how to reduce a photo in Photoshop without losing quality:

Clarification for Photoshop version CC 2016 and higher

After the release of this update, some changes were made to the application, which concern not only functionality, but also menu items. Now the “Save for Web” element is located along the path “File” - “Export”.

Please note that the “Export as” option is located above. “, clicking on which will open the updated interface of the compression utility.

The essence is the same, just in a different shell. I think it won't be difficult to figure it out.

How to reduce or increase the size of an image in Photoshop

Using Photoshop, you can easily reduce or increase the size of an image. Moreover, this can be done in different ways depending on what result you are striving for.

Before we start looking at the methods, first a little theory.

Firstly, what is reducing or increasing the size of an image? First of all, this concept should be understood as reducing/increasing the resolution of a picture, that is, its length and width and, accordingly, the number of pixels that make up any raster image. Learn more about resolution.

Secondly, what happens to the quality of the picture after resizing it?

• During the reduction process , pixels are lost, but the overall quality does not suffer, it remains quite clear.
• During the enlargement process , Photoshop stretches the pixels and draws them in accordance with its algorithm. Therefore, when enlarging, the picture quality always suffers. The higher the magnification, the more clearly the irreversible loss of quality is visible.

A similar issue was discussed in the lesson related to changing the layer size, I recommend you read it

A clear example of how image quality changes:

In this article, we’ll look at 4 ways to change the size of a picture in Photoshop and look at when and which method is best to use.

Method 1 - Image Size Dialog Box

This is the classic and most universal way. It is suitable in most cases, especially when you already know to what size you should reduce and enlarge the image size.

Open the image in Photoshop.

the Image - Image Size dialog box (or key combination - Alt+Ctrl+I). The following window will appear:

Immediately pay attention to the fields Width and Height . The values ​​that will be indicated there are the current dimensions of the image. By default they are measured in pixels.

If you initially know to what size you need to resize the image, then enter these values ​​in the above fields.

Proportions

If the Save proportions , then you can enter any values ​​in the length and width fields. But you risk that the picture will be stretched vertically or horizontally. It is very easy to make a mistake and choose the wrong proportions.

Example without maintaining proportions

It is recommended to check the box anyway. In this case, when you enter, for example, Width, Photoshop will automatically calculate what the height should be so that the proportions of the image do not change.

Example with maintaining proportions

Method 2 - Resizing using Transformation

Transforming an image is a cool method that definitely needs to be added to your Photoshop knowledge base. This method is good in two cases:

• reduce or increase the size of the entire image;
• Reduce or enlarge the inserted image in Photoshop.

Size details for each case.

How to reduce or increase the size of an entire image

Open the picture. Select the command Edit - Free Transform or press the key combination Ctrl + T.

If this command is not active (grayed out), then your background layer is locked to change. This is indicated by a padlock icon directly on the layer.

To unlock the background layer, double-click on it. New Layer window will appear , click on OK .

A frame will appear around the image. There are markers in the corners and on each side that you need to pull to make the image smaller or larger.

After resizing, click on the checkmark at the top of the options bar. There is a bug in Photoshop CS6 and this checkbox is not visible. If you also don’t see it, then press the Enter button to accept the changes or Esc to cancel.

Step 3.1 Magnification case

If you enlarged the picture in this way, then, as you can see, part of it became hidden, it seemed to not fit into the size in which it was opened. On the one hand, this is also not bad and can also be used in some cases.

But if you insist that the image be shown in full, select the command Image - Show All .

Step 3.2 Case when decreasing

When you zoom out, you'll see a checkerboard background. This is emptiness, transparency. It will disappear when you save the image. But it would be correct to cut off the void in order to ultimately see what the final size of the picture is.

To trim the void, select the command Image - Trimming .

In order not to disturb the proportions of the image in this method, when you drag the frame markers, simultaneously hold down the Shift .

How to reduce or enlarge an inserted image in Photoshop

In any case, take the case described above into account. Namely, the ability to use the Free Transform (Ctrl+T). This technique will be needed to carry out such a common operation as reducing or enlarging an inserted picture, item, object (call it what you want).

So, a familiar situation: you inserted another picture into your main image in Photoshop, but it did not fit in size.

Select this image and use the transform command. Now, as described above, pull the markers in the desired direction.

Method 3 - Canvas Size

Not the most popular method, but nevertheless we will also consider it - the Canvas Size command.

The peculiarity of this method is that we change the size of the image resolution, while the picture itself does not change in any way. Photoshop simply cuts off part of the image (if we are talking about reduction), or adds a background color (if we are talking about enlargement).

That is, let’s say your picture is 700x700 pixels. Through Image - Canvas Size you set the size to 500x500. As a result, Photoshop cuts off the extra 200 pixels in height and width. In the settings, you can specify where it cuts from: it is either evenly on all sides, or you can select a specific side.

Method 4 - Cropping

Cropping is done using the Frame , and it, in turn, is similar in its work to Canvas Size . It also does not change the size of the image itself, but only crops it, or adds emptiness if enlarged. I think we won’t dwell on this method in detail. Read more about the tool in this article.

How to reduce image size without losing quality

We looked at 4 ways to reduce image sizes. Of these, two methods: Canvas Size and Crop are not associated with loss of quality. In fact (width and height) the pictures become smaller, but the content itself remains the same size. To achieve this, you need to sacrifice part of the image, in other words, simply crop it to the desired size. For more details on how to do this, see the text above.

How to make a cropped image smaller in Photoshop

To reduce the size of a cut-out object in Photoshop, you need to be able to: cut out objects, manipulate the cut-out area (including reducing it).

Read about how to cut out objects in other articles. Let's look at reduction in more detail.

In this situation, knowledge of using the Free Transform .

When an object is cut out, you need to create a selection area around it. After that, apply a transformation and, according to the instructions above, drag the handles in the direction to make this object smaller.

In any case, when reducing the cut fragment in the free space, Photoshop will automatically add a background color. Therefore, if you have a simple case, then take care first and select the same background color that surrounds the object to be reduced. To do this, get a color swatch using the Eyedropper tool and set it as the background.

How to reduce the size of a picture without losing quality

How to reduce the size of a picture without losing quality , I became interested in the answer to this question when I wanted to make a miniature from an image for my PC desktop wallpaper for an article on my website.
Having typed the request into the search bar of my “favorite browser”, I began my journey through the sites, with the hope of quickly solving this problem.
But that was not the case, I tell you, dear ones, in the words of a well-known saying. In search of the right one for myself, I tried many of them. After all, high-quality images and design are the right way to increase traffic and promote the site (read the previous article), and the search engine gave me many articles where, with the help of various programs, “our brother blogger” works magic on his own and others (read downloaded from the “net” ") pictures.

Various ways to change image sizes and quality

1. Among them are: multifunctional, shareware, such as Batch Picture Resizer . I provide a list of its capabilities: resizing photos, renaming files and adding watermarks, batch processing of photos, converting formats. It can be downloaded from this link: https://yadi.sk/d/g6eDFTyzAMob6
2. And very simple ones, including PicSizer .

Download from the link: https://yadi.sk/d/ersMgoPIAMot8 from Yandex disk.

But as always, searching in the distance, we forget or don’t know about what lies very close.
After all, manipulations with image optimization can be done using standard means of the operating system itself. Let's say in order to reduce the size of a photo in Windows 7 you need to:

• Move the cursor over the object, right-click and select: Open using image and fax viewer and click Paint.
• Next: Menu-Properties and a sign pops up, and in the lower right corner there is a slider for changes. Use the slider or set the size and click OK.
• After that, “click “Save as ...” , here on the right are possible options for changing the image format.

Changing an image in Photoshop

But today, using the Photoshop program, I want to show you how to resize an image without changing the quality .
Well, along the way, the format is at your discretion. Let me make a reservation right away that in order to obtain a high-quality image, it is necessary to gradually reduce the image. That is, we will do it in two times. Open the program, load the image - File - Open .

After that, “click” -Image-Image size , as shown in the screenshot above. When the sign for changes appears (screenshot below), first make resize changes to half the original format.

And in order not to lose quality, we select below: Bicubic sharper (best for reduction) .
And as always, confirm the action by pressing the OK button. After doing all the steps again and getting the required size of the picture, you can improve its sharpness. This is so that it looks clearer and sharper on different browsers. We do it as in the screenshot below, following the path - Filter - Sharpening - and choose which one we want.

I think that the information I provided to you will be useful to you. After all, the question of how to reduce the size of a picture without losing quality interests all bloggers. Because loading images on a web page takes the lion's share of the time allotted for this action. And site performance, as you know, is important for promoting your resource.

At this point I have run out of information on this topic. And to you, dear visitors, a small request, when leaving, press one of the social network buttons. By doing this you will express your gratitude for my (your) work. Thank you .
Yes, sorry, I also completely forgot to remind you that the site has an interesting article on the topic of making money on surveys, and user reviews. Don't forget to ask about their conclusion.

Reduce video size without losing quality

Well, since it’s “such a heat”, in this same post I’ll tell you how you can reduce the size of the video .
True, I’ll say right away that there’s no way to do without loss of quality here, because the quality of all modern video formats lies in their “weight”. And this can be done in any video converter, starting with the Format Factory and ending with VideoMaster.
Everything will depend on what you prefer - paid or free options. Reducing the size is done by changing the video file format, and the easiest of them, as you probably know, is MP4.
