"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."

FI to IFF Conversion: FAQ

What are FI files?

FI is a rare and obsolete file format associated with Flash Image, an image handling program which is not very well known at the moment. For easier storing and transferring, FI images can be converted to more popular and widely accessible image formats, such as JPG, PNG or TIF.

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.
