"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."

It is a bitmap file that can store black-and-white, gray-scale and color images, and may also contain color maps and alpha channels.
