G3 to DCX 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 DCX files?

DCX files are multi-page images consisting of raster graphics, usually used to create fax files and functioning as a header that introduces a series of ensuing PCX files. DCX is a bitmap format and was initially developed together with the PCX format by Zsoft Corp. and was associated with PC Paintbrush. This graphics editing software was popular in the late 1980s on computers using the MS-DOS operating system, and later on it was adapted for Windows too.
