.JPEG File Extension

Compressed graphic format standardized by the Joint Photographic Experts Group (JPEG); supports up to 24-bit color, which makes JPEG a good format for storing digital photos; compressed using lossy compression, which may noticeably reduce the image quality if high amounts of compression are used.

JPEG images are commonly used for Web graphics and for storing photos taken with digital cameras. They are usually saved with a .JPG extension.
