JPEG

Stands for Joint Photographic Experts Group. A graphical file format that can be compressed to reduce its overall size. It is very widely used for photographic images for local storage, exchange, and placement in printed or web pages. Many graphics programs can compress and decompress JPEG files. It works with RGB or CMYK images, but cannot handle additional channels such as cut-out masks (for which TIFF or PNG can be used).
