What are JPEG Images

Definitions of JPEG on the Web:

• In computing, JPEG (, ) (named after the Joint Photographic Experts Group who created the standard) is a commonly used method of lossy compression for photographic images. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. ...

• This group defined a format for encoding photographs that uses fewer bytes than the pixel-by-pixel approaches of GIF and PNG, without too much visible degradation in quality. The format (JFIF) is casually referred to as JPEG. About JPEG pointers from W3C
