免费在线 G4 转 JIF 转换器

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).

JIF is a lossy format used for digital photography that was developed by JPEG (Joint Photographic Experts Group). Despite the fact that It is not limited to a certain number of colors and is based on a 24-bit color palette, part of the information is lost during compression.
