What can be done to a JPEG image without affecting the quality?
A typical image editor will decompress and recompress a JPEG file when you save it, resulting in a loss of image quality. You can avoid this if you use special software that can do a very limited set of operations that don’t involve recompressing, i.e., they just rearrange the data already in the file.
