Convert SFW to J2C
Convert SFW images to J2C format, edit and optimize images online and free.
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 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.
