Free Online G4 to JBIG Converter

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).

JBIG is a standard for lossless compression of image formats. Despite the fact that it was initially developed for fax machines, it can be easily used for other types of images. Files saved in the JBIG format are smaller in comparison with the other industry standard formats like G3 or G4.
