The SFW file extension stands for Seattle FilmWorks Image, a proprietary bitmap image format created by Seattle FilmWorks, a company specializing in film processing and digital imaging. Although the company is now defunct, SFW files can still be viewed using specific software or converted to standard formats like JPEG. This format is not widely supported by modern image editing software.
The JBIG (Joint Bi-level Image Group) file extension, standardized as ISO/IEC 11544 and ITU-T T.82 in 1993, is a lossless image compression format primarily used for binary images, such as those in fax transmissions. Developed by the Joint Bi-level Image Experts Group, JBIG offers significant compression efficiency over previous standards, achieving up to 50% better compression than Fax Group 4. Its history dates back to 1988 when ISO and CCITT collaborated to create a unified standard for bi-level image coding.
