Convert FAX to CALS

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 CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image file format, developed by the United States Department of Defense in the mid-1980s, is a standard for storing raster (bit-mapped) image data, typically black-and-white. It ensures efficient data interchange and retention of orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images. This standard was part of the broader CALS initiative aimed at improving electronic publishing and data management within the federal government.
