Convert FAX to PGM

The FAX file extension, short for "facsimile", is primarily associated with digital fax documents. These files are typically saved in TIFF format and are used to store images of documents sent or received via fax software. Historically, fax technology allowed the transmission of scanned printed material over telephone networks, a practice that became widespread in the 1980s and 1990s. Today, FAX files facilitate the digital handling of these documents, enabling easy archiving and viewing with compatible image viewers.

The Portable Graymap (PGM) file extension, originating in the late 1980s as part of the Netpbm project, stands for "Portable Gray Map". It serves as a simple, versatile format for grayscale images, enabling easy reading and writing by various programs. Due to its straightforward structure and plain text encoding, it's often used in academic and research settings where ease of parsing and accessibility are crucial. PGM files store grayscale images in a compact, efficient manner, making them an essential tool for image processing tasks.
