Sometimes it happens that you need to resize the image. The reason for this can be many factors. Firstly, the higher the resolution of the photo, the larger its size, and such files can be problematic to store on the device. Secondly, if you need to take a photo via the Internet, problems can arise, because some file hosting sites have the maximum allowable size limit for the photo.
That is why in the article we will talk about how to change the resolution of a photograph. This may come in handy at a computer, so let's get started.
What is permission?
First of all, let's see what permission is. And the term is basically simple: resolution refers to the number of pixels vertically and horizontally.
As you know, the more photos have those same pixels, the larger its size. However, in our time there are innumerable programs that can reduce the image, thereby reducing its size and without losing quality. Well, now let's talk more about how to change the resolution of a photo.
I would also like to say that if the number of pixels decreases relative to the original value, the photo will not lose quality, but if the same value is increased, the difference will become noticeable.
Method number 1. Paint
Everyone is probably familiar with the Paint program. But despite its small number of functions, it is able to help in changing the resolution of the photo.
So, let's say you have a photo with a resolution of 3,000 by 4,000, and you want to reduce this number by half. To do this, Paint opens. You can use the search by calling it using the Win + Q keys. There, immediately click on “File” and select “Open”. In the explorer that appears, indicate the path to the desired photo and click "Open."
Here is your photo. To change its resolution, click "Resize". This button is located on the top panel next to “Select”.
Now a small window has opened, in which first of all it is necessary to choose in what sizes the size will be changed. There are two options to choose from: pixels and percentages. We select the first. Now you need to check the box "Keep aspect ratio", this will prevent the case when the photo is narrowed or flattened.
Now you can start resizing. Since we initially wanted to reduce the photo by half, we enter the value “2,000” in the “Horizontal” field. You probably noticed that the “Vertical” field was filled in by itself, this is because the “Keep aspect ratio” checkbox is checked ".
Now click OK and we can safely save the photo in a new size: “File - Save”.
This was the first way to change the resolution of a photo - in Paint, now move on to the second.
Method number 2. Adobe PhotoShop
Now move from small to large, more precisely from Paint to PhotoShop. Of course, these are two image editors, but they are nothing alike, but this approach will not fundamentally differ from the previous one.
So, we begin to understand how to change the resolution of a photo in PhotoShop. First you need to open it. Right after that click “File” and then “Open” and make a path to your photo.
Now click on the “Image” item on the same toolbar. In the list, select the line "Image size ...". Or you can just press Alt + Ctrl + I.
In the window that appears, immediately check the box next to "Save aspect ratio." And in the “Dimension” column, select “Pix.” In the drop-down list. Now feel free to resize the photo.
After that, it remains only to save it, but this must be done in a slightly different way. Click File, then Save As ... and select the BMP format. This will preserve the image quality as the original.
Now you know how to change the resolution of a photo without losing quality using PhotoShop.
Conclusion
As you may have noticed, you do not need to know much to change the photo. Each of the above manipulations can be performed by everyone, but in the end you will get what you want: the photo will change, but the quality will remain the same, and the file size will noticeably decrease. We hope the article gave you an answer to the question of how to change the resolution of a photo.
