Double compression with Polish?

Can Polish end up over-compressing an image? For example, if I have a 70% compressed JPEG file, does it compress it again?

Polish only compresses if it can do a better job. It also depends on if you’ve set it to Lossy or Lossless. In both cases, the same rule applies: compress when it can improve file size.
