The highest compression rate (0 is lowest and 9 is highest) will make the smallest file, but it will also take the longest to save.

The ‘Compression level’ setting when saving PNG files determines the final file size of your image and also affects how long it will take to save. Each one has a quality/compression setting that you can adjust for your needs, but they don’t all work the same way. Usually, the highest-quality images have the largest file sizes, but compression allows you to shrink that file size down while maintaining quality – the trick is where you set it.Ĭompression level in GIMP appears when you’re exporting your finished work as one of the standard image file types like JPEG, PNG, or TIFF.

The simplest explanation is that compression level helps you balance image quality against image size.
