What is a PBM File?
A PBM file contains black-and-white image data represented as binary “1s” and “0s.” It is a raster image file in plain text format where each black pixel is represented by a 1 and each white pixel is represented by a 0. Since it is an open-source file, it has no developers nor any standard format.
