Convert FAX to FF

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 Farbfeld (FF) file extension stands for "Farbfeld Lossless Image", a format designed for simplicity and efficiency in parsing and piping image data. Introduced by the Suckless community, Farbfeld stores images in a straightforward, uncompressed format, making it ideal for use with external compression algorithms. This format uses 32-bit RGBA values for each pixel, ensuring lossless quality. Its history traces back to the need for a minimalistic, easily manageable image format that avoids the complexity of integrated compression found in formats like PNG.
