Please qualify "compress". Is your aim to save network bandwidth, save GPU space, or both?

If the latter two, then check out squish (article). Great DXT compression lib. There's also probably several libs and executable tools from NVidia (link1, link2) and/or ATI (link) you might use to help you out.

If you just want to compress for network bandwidth (or to compress further), look at zip, zlib, gzip, etc.
