JPG is one of the most recognizable, popular, and comprehensible bitmap image formats.This format appeared as a result of the work of the group of photo experts “Joint Photographic Experts Group”. The main task of this group of developers was to develop an optimal image compression algorithm. Today, this problem has been solved successfully. It is used .jpg most often for processing and storing full-color images with realistic images, where brightness and color transitions are inherently present. Also .jpg format is used for storing and transmitting graphic digital content (photos, scan copies, digitized pictures). It is most convenient for placing and transmitting compressed images over the network, because it takes up little space compared to other formats.
