The SFW file extension, created by Seattle FilmWorks, was used to store digital copies of photos processed by the company, allowing customers to receive both physical prints and digital images. Although not widely supported by modern software, SFW files can still be opened and converted using tools and older versions of image viewers. This format marks a significant step in the evolution of digital photography.
The G4 file extension is linked to the CCITT Group 4 Fax Image format, recognized by the International Telecommunication Union (ITU) for its ability to compress monochrome images without data loss. This format is integral to fax technology, employing a two-dimensional coding system that identifies image patterns, resulting in high compression ratios and minimized file sizes, key for efficient document transmission.
