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 JNG format expertly blends JPEG's compression with PNG's transparency. Developed by the PNG Development Group, it's a member of the MNG family, designed for embedding lossy JPEG images in animations. While JNG files are more compact, they may exhibit typical JPEG compression artifacts.
