The procedure for compressing the digital images in JPG format is carried out in several stages. A strong contrast between several near located pixels provokes the appearance of visible artifacts. It is not recommended to use this format for compression of drawings and various kinds of graphics. The JPG algorithm is optimally suitable for compressing photographs and pictures in which realistic scenes with little contrast of colors are present.
