JPEG

Joint Photographic Experts Group. JPEG represents a compressed image file. The JPEG compression algorithm allows a compromise between final file size and the amount of information which is lost in the compression process. (JPEG is therefore a lossy compressed file.) Be aware that if a JPEG file is opened and re-saved then yet more ... be lost. A JPEG file is normally denoted with either a ".jpeg" or ".jpg" file extension. See also JFIF, JPG.
