Unlike JPEG, PNG is a lossless compression format, more meant to be a 
substitute for GIF.  PNG (Portable Network Graphic) was created when GIF's 
patent issues reared their ugly head. 


Its actually better than GIF, because it supports alpha channels and a few 
other features not present in GIF.  You can almost consider it GIF 2.0.
