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

If the latter two, then check out squish (http://code.google.com/p/libsquish/) (article (http://www.sjbrown.co.uk/2006/01/19/dxt-compression-techniques/)). Great DXT compression lib. There's also probably several libs and executable tools from NVidia (link1 (http://developer.nvidia.com/content/texture-tools-208-64-bit), link2 (http://developer.nvidia.com/legacy-texture-tools)) and/or ATI (link (http://developer.amd.com/tools/compressonator/pages/default.aspx)) 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.
