Бесплатный онлайн конвертер SFW в G4

Format for bitmap images that were created in the Seattle FilmWorks video editor, which is no longer being actively developed. It was also used to create slideshows. The format has a MGI PhotoSuite file structure that supports bitmap images. SFW files can be converted into JPG images.

G4 is a method to compress black and white images without losing quality. It is used for fax machines and as a one of the compression types for the TIFF format. G4 treats a picture as black dots and lines on a white page (less file size will be achieved if there are less black dots and lines).
