[file extension] jpg or jpeg (pronounced jay-peg) [acronym meaning] Joint Photographic Experts Group [definition] 
a lossy data compression for color images especially effective for scanned photos. There are varying levels of compression with varying loss of detail. At the highest compression (lowest quality), it can reduce files sizes to about 5% of their normal size. Lossy compression throws away some of the graphic data every time it is used to save. It does not lose data when merely opening a file, as on the Internet.
