Hi,
You won't see 80-90% compression on jpeg or mpeg as they are already compressed formats. You can downgrade the quality using any number of image manipulation tools to reduce the size, but you won't get it with lossless compression like zip/gzip.
You might be able to get an extra 10-15% using bzip2 or something similiar.
Cheers,
Alex
