What is a PBM file?
PBM (Portable Bitmap) is one of the simplest image file formats, part of the Netpbm library. It supports only monochrome images (1-bit color), meaning each pixel is either black or white.
PBM files are text-based and easy to parse, making them useful for educational purposes and simple graphics storage. Our Online PBM Viewer renders these basic bitmaps instantly.
