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 JBG file extension stands for Joint Bi-level Image Group, a format developed for efficient lossless compression of binary images, primarily used in fax transmissions. Introduced by the Joint Bi-level Image Experts Group, JBG files store 1-bit raster images and offer superior compression compared to older standards like CCITT Group 3 and 4. Although initially popular for fax machines, the format has largely been superseded by JBIG2, which provides even better compression.
