JPEG

JPEG is a widely used method of lossy compression for digital images, especially photographs produced by digital cameras. It lets users trade off file size against visual quality, typically achieving about a 10 to 1 reduction in size with a loss of quality that is perceptible but broadly considered acceptable. The format was developed during the late 1980s by the Joint Photographic Experts Group, a standards committee combining representatives of the International Organization for Standardization and the body now known as the ITU-T, and it was released in 1992. JPEG became the dominant image compression standard worldwide and was largely responsible for the spread of digital photographs across the internet and, later, social media; by 2015 billions of JPEG images were being created every day.
