I don't know a lot about how this works, but compressing a file is saving a file in a way that makes it smaller in size.
This is useful for saving space on your computer or storage device, and for sending files. As far as I know, there are two types of compression, lossy & lossless.
Lossy compression removes "unnecessary" information as it compresses the file, which can be fine, but can also create problems depending on the type of file & how you will be using it. With some files, such as graphic files, you need to be careful especially if you are going to be making changes and saving it again. For example, if you use photo editing software and save as a low quality jpeg (aka jpg) file, then repeatedly open the file, make changes & save it each time in the same format, you will see a reduction in the quality of the image. On the other hand, if you aren't going to be making changes to the file and you are only going to be viewing the image on screen, low quality jpg format is fine.
Lossless compression does not remove information from the file, so you can safely save and re-edit your file as much as you like, but you can't reduce the file as small as lossy compression.
