- 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 WEBP file is an image saved in the WebP (pronounced "Weppy") raster image format developed by Google for web graphics. It is designed to reduce image file sizes over standard JPEG compression while maintaining the same or similar quality. WEBP files allow images to be downloaded more quickly.
