JPEG (JPG)
JPEG is a standard format developed by the Joint Photographic Experts Group. Through the use of superior compression techniques, this format allows the transfer of files among a wide variety of platforms. JPEG supports 8-bit grayscale, 24-bit RGB, and 32-bit CMYK color modes.
The JPEG format is commonly used on the Web. For more information, see “Optimizing bitmaps for the Web.”
