JPEG stands for Joint Photographic Expert Group, an international standards body that sets standards for creating and handling compressed digital images. The JPEG file format was designed to balance good visual quality and small file size, typically through lossy compression. The JPEG file format is widely used as a means of compressing digital images, particularly those produced by digital cameras.
