"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."

FRE to IFF Conversion: FAQ

What are FRE files?

The FRE image format is associated with medical equipment software used for magnetic resonance imaging (MRI). FRE files most likely contain images captured using an MRI device and can be opened with a limited number of image viewers. They can, however, be converted to a more accessible format, for easier transfer and storage.

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. Commodore was one of the first types of personal computers to gain wide popularity among home users. An IFF file most likely contains an image that was created or edited using an image handling program on an Amiga computer. IFF files are currently considered obsolete and uncommon, so opening them with regular image viewers might be difficult.
