"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."

"I deal with hundreds of images daily, and reaConverter has been a lifesaver. The Watch Folders feature lets me automate file conversions without lifting a finger. I set up a folder for incoming files and it automatically resizes, renames, and converts them into the formats I need. It's like having a personal assistant!"
