JPEG
Lossy image format
JPEG stands for Joint Photographic Experts Group, the committee that created this image compression standard.
In technical contexts, JPEG refers specifically to the compression algorithm rather than the file format: JPEG encoding, JPEG standard.
Most casual usage prefers the lowercase form. (Lowercase jpeg is the common file format.)
