JPEG (Joint Photographic Experts Group)

A JPEG (pronounced JAY-peg) is a graphic image created by choosing from a range of compression qualities When you create a JPEG or convert an image from another format to a JPEG, you are asked to specify the quality of image you want. Since the highest quality results in the largest file, you can make a trade-off between image quality and file size.

The reason for choosing JPEG for images with more complex color patterns is that this format enables you to save imageswith millions of colors, whereas the GIF option restricts you to 256 colors.

Along with the Graphic Interchange Format (GIF) file, the JPEG is a file type supported by the World Wide Web protocol, usually with the file suffix of ".jpg". You can create a progressive JPEG that is similar to an interlaced GIF.
