Convert woff to pgm

What is the difference between .woff and .pgm?

Description: A WOFF (Web Open Font Format) file is a web font file format used for embedding fonts on websites. It is essentially a compressed version of a font designed to be compact and fast to load, making it highly suitable for use over the internet. WOFF files support metadata and font licensing information, ensuring that fonts can be legally used and distributed. The format is widely supported across modern web browsers, providing a standardized way to include custom fonts in web designs, thus enhancing the visual appearance and typography.; 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.
