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 High Efficiency Image File Format (HEIF) is a modern image format designed for superior compression efficiency and enhanced image quality. Originating in 2015, HEIF was developed by the Moving Picture Experts Group (MPEG) and utilizes the High Efficiency Video Coding (HEVC) codec to store image data. It supports a wide range of multimedia applications, including single images, image sequences, auxiliary image items, and non-image items, making it highly versatile for professional and consumer usage in various devices and platforms. Its ability to maintain high image quality while reducing file size significantly improves storage efficiency and accelerates data transmission.
