What is a JPEG file?

JPEG (Joint Photographic Experts Group) is a lossy compressed image format introduced in 1992. The .jpeg and .jpg extensions are completely interchangeable — they refer to exactly the same format. The shorter .jpg extension became common on older Windows systems that required three-character extensions, while .jpeg is the full form of the format name.
