A JPEG file is a compressed graphic file format developed by the Joint Photographic Experts Group (JPEG). It can handle up to 24-bit colors and is reduced via compression algorithm, which could also decrease image resolution substantially if high compression levels are employed. JPEG files are sometimes used to save digital photos and images on the web.
In 1986, the Joint Photographic Experts Group was established. In 1992, the JPEG file format was proposed and adopted. It has existed since the inception of the internet.
