A PGM file is an older version of Raster Image File (RIF) that is also called a “portable graymap file.” These files are typically encoded using ASCII or binary with either 8-bit or 16-bit grayscale images containing different shades of gray and transparent pixels. These files work across all the popular operating systems, such as Windows, Mac OS, and Linux, and can often be viewed and edited using any text editor. If you are having trouble opening a PGM file, there are a number of software programs that will open these files. PGM files are one part of a group of similar files used by the Netpbm project. This project uses PBM files for black and white (no gray), PGM for grayscale, and PPM for full RGB color.

Grayscale image file encoded with either one or two bytes (8 or 16 bits) per pixel; contains header information and a grid of numbers that represent different shades of gray from black (0) to white (up to 65,536); typically stored in ASCII text format, but also has a binary representation.PGM files include a header that defines the PGM format type ("P2" for text or "P5" for binary), image width and height, and the maximum number of shades. While binary PGM files may contain multiple images, ASCII PGM files may only include one image.
