"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."

HDRI to IFF Conversion: FAQ

What are HDRI files?

SilverFast’s 64-bit HDRi RAW file is a TIFF that preserves a full 16-bit-per-channel RGB scan plus a separate 16-bit infra-red channel, giving 64 bits per pixel. The visible data stays completely unprocessed—no sharpening, gamma, or colour tweaks—while the IR map lets SilverFast’s iSRD (or compatible tools) later remove dust and scratches non-destructively, making it an ideal “digital negative” for archival film workflows.

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.
