PNG

Stands for "Portable Network Graphic." (No, it's not the same thing as the previous definition.) PNG is a file format designed primarily to replace the older GIF format (which has had some copyright issues limiting its use). PNG files, which are lossless (meaning they don't lose any detail when they are compressed) support up to 48-bit truecolor or 16-bit grayscale and typically compress about 5% to 25% better than GIF files. However, they do not support animations like GIFs do. A format similar to PNG, called MNG, is currently under development, and should support animations.
