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 J2C file extension stands for JPEG 2000 Code Stream, a format defined in Part 1 of the JPEG 2000 standard. Developed by the Joint Photographic Experts Group (JPEG) from 1997 to 2000, J2C files utilize wavelet-based compression, supporting both lossy and lossless compression. This format is primarily used for high-quality image storage and transmission, offering superior compression efficiency and flexibility compared to the original JPEG standard. J2C files are often embedded within other file formats like JP2 for enhanced metadata support.
