jpg: A compressed file format Java uses primarily for photographs. Such files usually have a *.jpg extension. JPEG stands for Joint Photographic Experts Group. Unlike *.gif, JPEGs never had patent problems. For photographs, JPEGs are more compact that *.png files but less compact that WIF files. Compactness is important since it reduces download time over the net. JPEGs are not good at line art. There you use *.gif or *.png. JPEG 2000, *.jp2 files, support transparency, but you don’t see them often. Axialis icon editor supports them.
