The term “JPEG” is an acronym for the Joint Photographic Experts Group, which created the standard in 1992. JPEG was largely responsible for the use of digital images and digital photos across the Internet, and later social media.
The JPEG compression algorithm operates at its best on photographs and paintings of realistic scenes with smooth variations of tone and color. For web usage, where reducing the amount of data used for an image is important for responsive presentation, JPEG’s compression benefits make JPEG popular. JPEG/Exif is also the most common format saved by digital cameras.
