JPG (or JPEG) is a popular digital image format which contains compressed image data. JPG/JPEG is one of the effective image compression methods, with a compression ratio of several tens of times. However, the image after decompression will be different from the original image. Image quality is degraded after decompression. This attenuation increases with the compression coefficient.
