"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 PCT 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 PCT files?

PCT is an image file format associated with Macintosh QuickDraw, a graphics program developed in the 1980s as part of the Apple Macintosh operating system. The initial version of the format, called PICT 1, could store 8 colors, while the later developed PICT 2 supported 24 and 32-bit color images.
