"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."

C4 to IFF Conversion: FAQ

What are C4 files?

A C4 file represents an Edmics or Jedmics bi-level raster image. Jedmics stands for "Joint Engineering Data Management Information and Control System" and represents an initiative of the US Department of Defense. C4 Jedmics files contain bitmap images intended for military use and are considered very rare files.

What are IFF files?

IFF is an old image format associated with Amiga computers — a brand connected to Commodore, which used to be popular in the 1980s and 1990s.

An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer.
