The CAL file extension, known as CALS (Continuous Acquisition and Life-cycle Support) Type 1 Image, is a 1-bit black-and-white raster image format developed by the U.S. Department of Defense in the mid-1980s to standardize graphics data interchange for military documentation. It is primarily used for storing and sharing monochrome images while retaining orientation metadata. The format supports both uncompressed and compressed (using CCITT Group 4 compression) images.
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.
