Compressing Model/Skin Files

[Deep Sea Kraken]

Is there a way to compress model/skin files? Because Ive been looking around and most of the ones I see are about 20-40kb. My friend made me some and they're about 100-220kb each. I'm not using enough to make the map file too large, but there are others I would like to have and it would just make the map file too big. Any ideas?
