Portable Network Graphic

Quick Info

The PNG format was designed by the W3-Consortium as a replacement for the patent-protected GIF format. It supports alpha channels, interlaced images, LZ77 compression and was made to be platform independend. Since it often provides even better compression than GIF and it has an improved interlacing method, it will surely become more popular soon.

Here is a list of programs which already support PNG: http://quest.jpl.nasa.gov/PNG/pngapps.html
