Gratis Online G4 naar SIXEL 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).

SIXEL is a bitmap graphics format developed by DEC (Digital Equipment Corporation) to use on printers and terminals. Such image consists of six pixels high and one pixel wide represented as an escaped sequence. If you want to open a SIXEL file but do not have a DEC terminal, the only way is to convert it to another more common format.
