"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."

What are CPI files?

The CPI extension is attached to vector files created using Calamus, a piece of desktop publishing software released in the late 1980s. Calamus was designed for the Atari ST, which was an innovative brand of home computers at the time, and was one of the first vector handling programs to include its own proprietary vector formats, as well as support virtual objects and frames. Since its release, Calamus had several subsequent upgrades and its latest version is Calamus SL2006.
