"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."

FUN to ICO Conversion: FAQ

What are FUN files?

FUN is a rare image format associated with some old drawing programs created for Commodore 64 (C64) computers. The C64 was an 8-bit personal computer launched in the early 1980s, but which still represents the best-selling model of home computers of all times. The FUN and FP2 extensions were attached to files created or edited using Funpaint or Fun Painter II — 2 programs which have now been long discontinued by their developers.
