How It Works

reaConverter offers the fastest, simplest solution for converting your GLTF files into IFF without 3D or CAD software - all models processed on your PC for maximum privacy and speed.

3D Workflow

From 3D model to picture

Product pages, manuals and reports need pictures, not GLTF files. reaConverter renders each model to IFF at the angle you set, a whole folder at a time.

  • Set the camera angle on X, Y and Z, or start from the isometric preset
  • Use one angle and size for every model, so a catalogue looks consistent
  • Script the job from the command line for pipelines and scheduled runs
  • Draw isometric, top, front or side views as line drawings with 2D projection

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.
