"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."

GG to AVIF Conversion: FAQ

What are GG files?

A GG file represents an image associated with Koala Paint or Koala Painter — a drawing program included on the Koala Pad. This device represented a low-cost tablet released in the 1980s by Koala Technologies, designed as a drawing pad for children. Koala Painter was also released for the Commodore 64 computer, and was fairly popular among home users during the 1980s. GG files are currently considered obsolete.
