Communication with computers is essentially made through the screen, so the image quality plays a vital role. Thus, graphics are becoming increasingly complex to respond to market demands (games, education, desktop publishing, graphic interfaces like Windows). Hence there is a need to introduce different methods of compression of graphic files. In this regard, several methods exist: No-loss (the result after decompression is identical to the original) and with loss (There is a loss of quality). This method is much more beneficial to the images because it significantly reduces file size by interfering minimally the quality of the final image. The format that we decided to study is the JPEG (Joint Photographic Experts Group).
