- Description
- A PGM file is a grayscale image file saved in the portable gray map (PGM) format and encoded with one or two bytes (8 or 16 bits) per pixel. It contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536). PGM files are typically stored in ASCII text format, but also have a binary representation.
- A JPEG file is an image saved in a compressed graphic format standardized by the Joint Photographic Experts Group (JPEG). It supports up to 24-bit color and is compressed using lossy compression, which may noticeably reduce the image quality if high amounts of compression are used. JPEG files are commonly used for storing digital photos and web graphics.
