G3 to GBR Conversion: FAQ

What are G3 files?

A G3 file most likely contains the digital image of a document that was either sent or received by fax. Such files use a type of compression called "Group 3", meant to efficiently minimise file size by compressing the white space which generally predominates in faxed documents. G3 files were mostly used during the fax machine era and are currently considered rare and obsolete.

What are GBR files?

GBR is part of the Gerber group of formats — a set of standardized extensions used in the printed circuit board (PCB) industry.
