How to resize an image without losing quality. Paint and PhotoShop programs
Good day, faithful readers and guests of the blog! Today's article is a short tutorial that will explain to you how to enlarge a photo without losing quality on your computer. To do this, I have attached some instructions on how to resize an image in Photoshop and Paint.NET.
In addition to this, I will also tell you about other applications and online services that allow you to change the scale of graphic files. Let's take a closer look at the material!
Working on the scale of pictures in Paint.NET
Everyone knows the standard Paint program, which allows you to resize images by the number of pixels or by specifying a percentage. However, it cannot keep track of the drop in picture quality when it is scaled. Therefore, now we will talk about another free raster graphics editor - Pant.NET.
The named editor was created by two students specifically for the Microsoft Windows operating system. Now this is a fairly powerful and convenient photo and picture editor, which we can use to achieve our main goal - high-quality image enlargement.
To do this, you need to perform a number of actions:
However, do not forget that a very small picture cannot be enlarged many times and still expect a perfectly clear result. At least not with this program. It is suitable for minor changes.
Using Photoshop Features
I'm sure you've all heard about this multifunctional and powerful graphics editor. It allows you to solve really complex problems and copes with them perfectly. The guides I've attached below will work for many popular versions of Photoshop, including CS5 and CS6. Remember to increase the canvas size before scaling the file.
So, the first option is to use the Image Size command. To do this you should:
1. In Photoshop, go to the “Image” tab and select “Image Size”;
2. In the dialog box that opens, specify the image size in pixels or percentages:
3. Check the last three items: “Scale styles”, “Keep proportions” so as not to distort the graphic file, and “Interpolation”;
4. And here is the most interesting thing. Interpolation directly affects image quality. When the resolution is reduced, some of the pixels are discarded, but when the resolution is increased, the program generates new similar pixels to fill the missing amount. This is why the output images look blurry
Photoshop offers several interpolation methods:
- By nearest pixels. Fast but inaccurate method. It maintains clear boundaries, which means that when you enlarge the photo, you may notice stepped lines. More suitable for illustrations.
- Bilinear. Interpolates horizontally and then vertically. The output is a smoother image, but the quality leaves much to be desired.
- Bicubic. Quite a slow method, but more accurate. The output tonal gradations are smoother, without visible jagged edges.
- Sharp bicubic. Used to make images smaller. Sometimes the sharpness of individual details is exaggerated.
- Smoothed bicubic. Just used when enlarging graphic files.
Choose one of them;
5. Click OK.
There is one drawback to this method. If you resize an image several times, its quality will deteriorate significantly as the program will add and/or remove pixels depending on your actions.
“Is it possible to bypass these negative consequences?” - you ask. Answer: yes. Immediately set the desired size to the old picture, or use this “ear trick”:
- In the “File” tab, select “Open as smart object...”;
- After this, stretch the image to the desired size;
- When scaling is complete, press Enter.
In this case, no pixels will be lost during resampling. And upon completion, the graphic file will be slightly blurred.
Either way, you can add contrast and sharpening to increase clarity.
Other software solutions
In addition to the editors mentioned above, there are other software solutions that allow you to adjust the size of graphic files in pixels and percentages. Let's look at some of them.
IMGonline.com.ua
Official site: https://www.imgonline.com.ua/.
I really like this online editor as it includes a wide range of features and functions for scaling, editing, compressing, converting, modifying, etc. images.
When enlarging a photo, the service prompts you to set the width and height of the canvas (while maintaining the proportions, you can set only one parameter), select a pixel distribution algorithm, set the format and its quality. The result is decent quality files.
Imagener
Official site: https://www.imagener.com/.
It is a paid program and is suitable for Windows OS. This is one of the best applications for enlarging image files. Available in three versions: Enhanced, Professional and Unlimited.
The cheapest version - Enhanced - allows you to increase the resolution of photos without a noticeable loss of quality by 300%. More expensive versions by more than 400%.
Pxl SmartScale 1
Official site: http://www.extensis.com/font-management/suitcase-fusion/.
One of the most expensive programs and not surprising. It allows you to effectively interpolate images up to 1600% without visible loss in quality! For those who want to try out the app, there is a free 30-day trial.
Enlarge 1.32 Beta
Official site: http://iproc.ru/software/enlarge/.
A free console utility that uses its own algorithm to scale graphic files. You can enlarge the picture 2-5 times.
Unlike paid software products, it is slower and does not have a graphical interface, although the quality of the output data is not inferior to commercial solutions.

Let’s imagine that the question of how to resize picture without photoshop? At the same time, you are on the Internet, and you need to crop a photo or picture for the questionnaire. You will do the right thing if you sit at your computer, or with a tablet, or with a smartphone in your hands, and go to the site.
After all, on this resource you can use an application for cropping photos online. Please note that the application supports gif, bmp, jpg, png formats. It is located in the “Working with Images” block called “Cropping Images”.
And, performing simple operations here, we resizing the image. After all, like everything else within the service, this application is very easy to use. It provides the opportunity to get high-quality results very quickly.
With his help we resize photo. We trim it. And to do this, you just need to upload the desired image, select the fragment you need to trim and press the “Cut” button, having previously received information about the size of the future image. That is, the process involves a percentage increase or decrease in the image. There is always the opportunity to see how you cropped the photo and then save it.
What other features does the application provide?
When we resize a photo online, this does not mean that the whole process, which takes a matter of seconds, boils down to simply cropping the image online.
Anyone working with the image can still spend additional (but literally just a matter of) seconds to rotate the photo or flip it if necessary. But this is not all there is to it. You can also add beautiful effects or a frame. And all it takes is a few clicks.
It is not surprising that the site’s users are people of various professions, ages and even hobbies. This is because some people prefer not to search for the application they need on various Internet resources. And this online service is good for many because it concentrates a wide variety of but frequently used applications.
And many of those who spend a lot of time on the World Wide Web (including in order to change photo), end up on the site quite naturally. Whether he is a designer or a webmaster, a journalist or a motorist. After all, many links on the Internet lead here, and the service is available to everyone without registration.
The service is also free. It can be used when preparing photos and music for blogs and websites. In addition, there is no need to download files, install and subsequently update programs.
This is appreciated both by those who are engaged in professional photography and by those for whom spending time with a camera is simply a great hobby. After all, the site has a suitable application for them. For example, for someone who is tormented by the question, how to resize an image?
Why is such a function needed?
The reason why one or another Internet user is forced to look for an online photo editor to use may be different. But, as experience shows, this is usually caused precisely by the need to quickly resize photo.
And this is usually the case. Let's say someone needs to upload an editable image to a website. For example, as a VKontakte avatar. As a rule, on most resources on the global network, images that are uploaded to the service have a size limit. And this in this particular case means that you need to resize the photo online.
There is no way to do without this. However, the limitation is not only for dimensions. The limitation also applies to the weight of the image. That is, the problem requires such a solution when you need to reduce the photo. And this is very easy to do using an online photo editor.
But the “enlarge photo” function is used when it is necessary to increase the size of the image. Just like photo reduction, this function is used when someone processes an image very often.
For a more detailed description of the popular service, we should also mention such a “trick” as Instagram-style photos. That is, in this case, the service provides the opportunity not only resize, but also to give the desired look to the photographs. Moreover, we are talking about those cases when you do not have a mobile device and an Instagram account with you.
We assure you that processing photos on a personal computer is much more convenient and enjoyable. The “Instagram style photo” feature works exactly the same as online photo cropping. This means the following: you need to upload a photo, apply effects and then save it to your computer. So, in particular, you can create the effect of an old photograph from an ordinary photograph.
Hello my readers!
Resizing an image is a fairly important operation not only for those who create and fill their own, but also for everyday use, from social networks to chats and forums.
There are a large number of programs that will allow you to change the resolution of the picture. But how can you ensure that the photo does not lose quality during such editing?
This is what I would like to talk to you about today. If you are wondering how to resize an image without losing quality, then you are in the right place.
PAINT
First of all, I would like to talk about the standard Paint photo editor. The set of functions of this utility is not large, but the basic capabilities are inherent.
Launch the Paint program on your PC, in the “File” tab, select “Open”. In the window that appears, we find the desired image, indicating the path to it by sequentially opening the necessary folders.
Navigating the program is very simple: next to the “Select” icon you will find the “Resize” function we need, so select it.
The window of the image editor itself appeared in front of us. We can change the size in two parameters: percentages and pixels. We select the pixels and check the “Maintain proportions” box; this will make it possible to preserve the very shape of the picture, which will not reduce the display quality. When maintaining proportions, you only need to enter one parameter (width or length), and the second will be selected automatically. It's actually quite simple, isn't it?
After the manipulations have been completed, save the file in a format convenient for you.
Manual editing is also available in Paint. To do this, you need to select the entire image (press CTRL + A), then move the cursor to the lower right corner of the picture and move it to the upper left, the size will change.
After you have achieved the desired result, left-click on the unselected area and adjust the program’s working canvas to fit the image. Unfortunately, it is very difficult to maintain the proportion in manual mode.
It should be noted that with the help of Paint you can both increase and decrease the size of any picture.
Adobe PhotoShop
If you want to master all the features of this program, then I recommend that you take the course " Photoshop from A to Z in video format" After completing the course, you will be able to create miracles with this software, even if now you know almost nothing.
Changing the size and weight of a photo using this software is considered a universal method. Despite the range of possibilities, editing of this nature in PhotoShop is very simple.
To begin with, you actually need to have Photoshop installed on your computer. If this software product is already installed on your PC, right-click on the photo and select the “Open with” option, find PhotoShop among the entire list and select it.
Or first run the program, and then go to the “File” - “open” menu.
On the toolbar you will see the “Image” section, select it. In the menu, select “Size...”, after which the image editing tool will be launched.
After these manipulations, save the files in BMP format. In this case, there is no difference between the original and the reduced copy. Or, leave the JPG format, but when saving in the “Image Quality” block, instead of the number 8, put 10, this will give the maximum quality to the picture.
If you save a picture for the purpose of later posting it on the Internet, for example, on your blog, then it is better to save it in a different way (so that it weighs less). Look at the screenshots below:
In addition to these options, there are hundreds of other types of software online that perform similar functions. You can also use online services, they also do an excellent job of their duties, as a rule, they all have detailed instructions.

How often, while looking through photos on the computer, we have thrown away great shots because they turned out to be too small in size and of poor quality. But with the help of special programs you can save almost any image!
Improving image quality is a very voluminous topic. To improve the quality of photos in Photoshop, color correction, sharpening, retouching and many other operations can be used. All of them require certain skills and mastery of special techniques.
But there are also less complex methods when you simply need to enlarge the image without losing quality. Below we will look at an example of how to improve the quality of a photo if you need to enlarge the photo without losing quality.
How to enlarge a photo without losing quality
We've all had to deal with small, low-quality images. In such photographs, when enlarged, the pixels, the points from which the raster image is constructed, are clearly visible.
Enlarging the image by stretching it and freely transforming it will only make the situation worse.
In this tutorial, the work will be done in Photoshop CC 2017. But first we will look at the method for other, older versions of Photoshop. And then we'll show you how Photoshop CC 2017 can do the whole procedure automatically.
Open the image in Photoshop. Now we will gradually increase it in several passes. It’s worth noting right away that you can enlarge a photo and improve the quality, but with a size limitation.
Press the key combination Alt + Ctrl + I. A window will open "Image Size". It is necessary that between "Width" And "Height" a paperclip was pressed. Then the width and height will change proportionally.
Let's enlarge the image twice, each time by 20%. To do this, in the drop-down list opposite "Widths" change the pixels to percentages (Pixel/Percent), and the numerical value from 100% to 120% and click Ok. Then call the image size window again ( Alt + Ctrl + I) and increase by 20%.
We increased the image size from 950x632 pixels to 1368x910 pixels.
For a visual comparison, let’s zoom in on the original image (950x632 pixels) and the resulting one (1368x910 pixels).
We enlarged the image by almost one and a half times and even improved the quality. As you can see, the pixelation is less noticeable if you zoom in on the image.
It remains to finalize the result. Let's apply a filter "Smart Sharpen" to the resulting image.
Let's go: “Filters”/“Sharpening”/“Smart Sharpening”/Filter/Sharpen/Smart Sharpen. Move the sliders to select the appropriate sharpness. If you left-click and hold on the image in the small preview window, you can see the image before the effect is applied. The difference is noticeable. The smooth transition of color (without cubes) on the lenses of the glasses is especially noticeable. We removed the noise completely by moving the slider all the way to the right. The sharpness radius was taken at 0.3 pixels, the effect was applied at 79%.
Let's compare the results again.
On the left is the original image, in the center - after resizing, on the right - with application "Smart Sharpening".
After use "Smart Sharpening" The noise in the photo has gone away and the image has become clearer.
Here is our result.
Now let’s enlarge the photo and improve its quality using automatic tools in Photoshop 2017.
Open the image in Photoshop, press the keyboard shortcut Alt + Ctrl + I. A window will open "Image Size". Please note the point “Fit to”/Dimensions. Expand this list. In it you will see blank options for enlarging/reducing the image without losing quality. Let's use automatic selection (second item in the list). In the window that opens, select the item "Good" and press Ok. There is no point in choosing the best one, since the original image is of too low quality, and there is no point in enlarging it that much.
Please note that if we managed to enlarge the image from 950x632 pixels and a resolution of 96 pixels/inch to 1368x910 pixels with the same resolution, then the program increased it to 1969x1310 pixels with a resolution of 199 pixels/inch.
Let's apply Smart Sharpening.
Now you have seen for yourself that you can enlarge a picture without losing quality, and at the same time even improve the quality of the photo.
It is worth noting that this method can be useful not only for enlarging and improving small photos. For example, you need to provide a photo for an online resource or for printing in a publishing house. Your photo is of excellent quality and large size, but the publishing house needs an even larger size. By applying the described method of enlarging a photo and improving its quality, you will get an excellent result. After all, large photos with good quality will go through this procedure much easier.
The procedure is extremely simple. Don't give up on small pictures. Give them a second chance.
