Stands for "Portable Network Graphic." This format was designed as an alternative to the GIF format (which has been plagued by copyright issues). Like GIFs, PNG files are lossless, meaning they don't lose any detail when they are compressed. They support up to 48-bit color 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 will support animations.

File extension: .PNG
