"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."

IDC is a bitmap format created or edited using programs developed by Core Software. IDC files are currently considered rare and in case you found such a file it was probably created a long time ago and might be difficult to open with regular image viewers.
