What is a PNM file?
A PNM file is a generic term for the Portable Any Map family of image formats — an umbrella name covering PBM (Portable Bitmap), PGM (Portable Graymap), and PPM (Portable Pixmap). PNM is not a single format, but a collective name for these three plain, uncompressed raster formats developed as part of the Netpbm toolkit. PNM files can store black-and-white (PBM), grayscale (PGM), or full-color RGB (PPM) images.
PNM emphasizes simplicity and portability — files can be stored in plain text (ASCII) or binary (raw) format, making them easy to generate, parse, and debug.
What is a PNM file used for?
PNM files are mainly used for:
They provide a minimal, cross-platform way to handle basic raster images without compression artifacts.
How to open a PNM file?
PNM files (i.e., .pbm, .pgm, .ppm) can be opened with:
pnmtopng, pnmquant, etc.) Note: Files may use .pnm extension generically, but most tools expect the specific extension (.pbm/.pgm/.ppm) to detect type.
Is a PNM file an image file?
Yes.
A PNM file contains actual pixel data — either 1-bit (PBM), grayscale (PGM), or RGB color (PPM) — stored uncompressed and unencoded.
