JPG or JPEG (an abbreviation for the name of the company developer Joint Photographic Experts Group) - the most common graphic file format. JPG is a raster image format, that is, an image consists of individual pixels. This format supports compression, based on its own algorithms, due to which the image file takes up less disk space. The degree of compression can be determined by the user, including saving the image in its original form (lossless).
The format has gained great popularity on the Internet, including due to the small size of files while maintaining good quality images. That is why the conversion to JPG is so in demand. However, the format also has drawbacks that are worth remembering - lack of transparency, animation, as well as a loss of quality during repeated processing.
