"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."

CALS to DIS Conversion: FAQ

What are CALS files?

The CALS image format includes a compressed raster/bitmap file. Though considered rare by mainstream users, CALS files are used by many document-handling, DTP and image processing applications employed by the US government. The format itself was created by the Department of Defense as a standard for storing an interchanging graphics data. CALS stands for "Computer Aided Acquisitions and Logistics Support", which is an office inside the Department of Defense.

What are DIS files?

The DIS extension is associated with the DKB Ray-Tracer, a piece of software originally created by David Kirk Buck and Aaron A. Collins, which served as a predecessor for the POV Ray-Tracer.
