How to quickly compress photos. Reducing image size using the Snagit editor

As you probably know, in last days I was closely involved in site optimization. During this time I learned a lot of new and useful things.

We will talk about a service that will compress your pictures or photos in a matter of seconds without loss of quality and stronger than the famous standard in this matter - Photoshop.

Oddly enough, but this is really possible. The fact is that the creators and owners of this service have developed and apply their own crazy image compression algorithm... I repeat - without loss of quality!

I won’t talk about why you might need to compress pictures or photos. Everyone has their own reasons - some want to put a million photos in their email, others want to social network post... I’ll just describe the sequence of actions to obtain the expected result.

Compressing images with this service is a pleasure. Everything is so simple that I don’t even know how to describe this process to you. And the main thing is whether it is necessary to describe it at all, since everything is already intuitively clear.

Image compression service

And we see the following picture...

As you know, I use modern and convenient browser, so it translates all foreign sites for me automatically. You can have this page completely on English language. It's not scary or important at all.

On the right, at the top, select the format with which we will work...

Now let's go down to the three buttons...

...and press the left button...

We select, or rather, indicate images to compress on our computer (but no more than 20 at a time)…

Such empty squares should appear - we don’t pay attention to them and click on the middle button...

Now left-click on the square with your image...

All you have to do here is move the slider that lives on the right, select the degree of compression (observing the changes in real time) and save the result by clicking the “COMPRESSE” button. The compressed image will be downloaded automatically to your download folder specified in your browser.

You can move pictures using the vertical buttons on the sides...

That's all. The degree of image compression is truly amazing, I have never seen anything higher - I took this service into service so that the site continues to fly in your browsers.

Bye Bye! Until new useful and interesting programs!

Let's look at how to compress a photo without losing its quality. There are several ways to compress photos, and we will look at the free, paid and online methods.

Modern cameras Capable of taking high-resolution images, which allows you to enjoy the excellent quality of the photographs taken. But we must remember that high resolution The image “pulls with it” a large file size. For example, modern 8 Mpxl cameras produce photos with a size of more than 10 MB, and this is not very convenient when sending several files via e-mail or simply when posting a photo on a social network. For example let's take a drawing with a resolution of 3200x2400 pixels and its size is 2.06 MB.

Let's figure out how to compress a photo so that it has no visual differences from the original.

I. COMPRESS A PHOTO USING FREE PROGRAMS

Into the standard set of programs operating system Windows includes an application such as Paint. This is a fairly simple graphics program that will help you compress pictures. So, open the photo with Paint programs , Pressing the required file right-click and select " To open with» — « Paint».

From the main menu of the Paint application, select the " Drawing" and click on the link " Stretch/Tilt».

Now specify the compression ratio pictures as a percentage (for example, twice is 50%).

Click the "OK" button to confirm the changes and save the resulting drawing. Make sure its size is smaller than the original.

Compressed image using Paint:

And here is the original picture:

The quality of the picture has changed slightly, but visually the photograph does not differ from the original, according to at least There are no dramatic changes observed on the monitor screen.

II. COMPRESS A PHOTO USING PAID PROGRAMS

There are many professional graphics programs, which can easily compress any photo to the required size. The most popular application is Photoshop, but it has a whole set of powerful functions and add-ons, so installing such a cumbersome and expensive program just for compressing images is not appropriate. We suggest you pay attention to a cheaper version of the program for viewing and working with images Picture Manager , which is included in the standard package Microsoft Office. Install this application and use it to open the required photo.

Go to the section " Drawing" and select the item " Resize».

Set the picture resolution, selecting it from the standard options or entering a custom width and height.

It is also possible to set the percentage reduction of the image from the original dimensions. Confirm the final dimensions of the photo by clicking the " OK" Save the modified drawing and check its quality and size.

By the way, it works on the same principle ACDSee program and the image size after compression is much smaller.

III. COMPRESS A PHOTO ONLINE

For those users who do not want to bother with installation additional programs or are unable to work with standard applications, I have an opportunity compress photo online. To do this you need to go to website http://www.radikal.ru and upload the required drawing to this resource. Leave all the values ​​in the “” window unchanged, only in the “Reduce to” field set the width in pixels that the photo should have after compression.

Click the button Upload file" and select the required picture, then click the " button Open" And " Download" The photo will be uploaded to the server and automatic compression.

To download the resulting image, simply insert the link from the “ 1 " V address bar browser and save the displayed image.

Check the quality of the resulting image and make sure that file size has decreased.

Now you know three ways to compress a photo, and you can easily “adjust” your photos to the required dimensions. Ask all questions in the comments.

The main thing is to indicate the image on your computer or phone, specify the quality from 1 to 100, and click OK at the bottom of the page. The rest of the settings are set to default. How more indicated " quality» in settings (80-100), themes the size will be larger file. And vice versa, lower quality(50-75) will give smaller size JPEG file. If necessary, you can find out the level of quality (compression) with which the jpeg file was created.

If after compression the size jpeg file On the contrary, it has become larger than the original, which means you need to lower the quality level from 80 to more smaller number, for example, set to 60. The dimensions in pixels and megabytes before and after compression can be seen after processing or pressing the OK button. If, at a quality level of 40-50, the size is still larger than the original, then there is no point in compressing the image - it was already well compressed. You can only try to remove the metadata embedded in the jpg file or remove exif + make the jpg progressive without losing quality.

In the settings you can select the type of subsampling (decimation), which allows you to achieve greater compression jpg file with minimal losses. Subsampling 1x1 gives the best image quality, bright color transitions are preserved, mainly suitable for high-quality previews or small preview images. 2x1 subsampling is the most common method, used in almost all digital cameras, compression of sharp color transitions occurs horizontally, allows you to achieve a smaller file size without much loss, great for large images. 1x2- the same as 2x1, but only the averaging of sharp color transitions will be vertical. Subsampling 2x2 averages sharp color transitions horizontally and vertically, allows you to achieve the smallest file size, and is suitable for blurry pictures.

The original image is not changed in any way. You will be provided with another processed image in jpg format.

The photographs of "Red Pepper After the Rain" indicate the level JPEG quality for comparison:

Dimensions of this jpg pictures depending on the quality level (Q is quality, KB is the size in kilobytes):
Q 10 = 2 KB; Q 15 = 2.7 KB; Q 30 = 4.3 KB; Q 50 = 5.9 KB; Q 60 = 6.7 KB; Q 70 = 7.9 KB; Q 80 = 9.8 KB; Q 90 = 14.1 KB; Q 100 = 46.5 KB.

From the above examples it can be concluded that best ratio size-quality can be a quality level from 75 to 95. And in order for the picture to occupy the smallest size and at the same time be more or less normal, a quality of 60-70 is suitable. If quality does not matter, but you need small size file, then a quality percentage from 30 to 50 is suitable.

Please note that the file size progressive JPEG pictures are usually 2-3% smaller than the standard one with the same image quality, and they will also open beautifully when loaded into an Internet browser, as is usually done in films! An example of a standard and progressive JPEG image can be viewed.

Hello friends!

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 post pictures in your materials big size and weight.

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 right size for printing, for posting on a website, to reduce the same weight of the picture, since it decreases when the size is reduced.

Weight reduction may be necessary to save weight on the media ( HDD, flash drive and so on), for fast loading images on the site and so on

Options indeed great amount. 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, as this can be done using standard set programs and even a standard operating system editor Windows systems- 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 consider the option with 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. A suitable method also for any need.

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 has a name 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.

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

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. All the methods described in the article, how to the average user Internet, you will be in over your head.

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.

Best regards, Konstantin Khmelev!
