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.

FAQ

RAW to CG4 Conversion

What are RAW files?

Also known as "digital negatives", RAW photos are uncompressed images that include all the details captured by the camera's sensor. They need to be post-processed using an advanced image editing software. Shooting in RAW mode allows the photographer to have more control over how the image will eventually look, compared to the case of other compressed formats, such as JPG or PNG. The downside of using RAWs, however, is their enormous size, which makes them difficult to store and transfer.

What are CG4 files?

CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
