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.

PNG is short for Portable Network Graphic, a type of raster image file, commonly used to store web graphics, digital photographs, and images with transparent backgrounds. PNG is an image format that uses a new data compression method - without losing the original data. PNG was created to improve and replace the GIF image format with an image format that does not require a patent to use.
