"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

G3 to DIS 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 DIS files?

The DIS extension is associated with the DKB Ray-Tracer, a piece of software originally created by David Kirk Buck and Aaron A. Collins, which served as a predecessor for the POV Ray-Tracer. The latter software has the capacity to generate images from text-based scene descriptions and works on various platforms. Though fairly popular on PC/MS-DOS platforms at its release, the DIS format is now obsolete. It can, however, be viewed and converted to more accessible formats.
