Why would you want to compress images?
Depending on the source of an image, the file could be quite large. A JPG from a professional DSLR camera, for example, could be dozens of megabytes. Depending on your needs, this could be too big. Compressing this image would be very useful.
Likewise, you might have large images on your phone. These images could be taking up a lot of hard drive space and preventing you from taking more photos. Compressing them could free up more internal storage, fixing this problem.
