"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."

OFX to IFF Conversion: FAQ

What are OFX files?

OFX is an archaic image format associated with fax machines developed by Dutch company Olicom. Such devices were mostly used in the 1980s and 1990s, so in case you came across an OFX file it is probably very old and represents a digital copy of a document that was sent or received through fax.

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.
