Step by step

How It Works

reaConverter offers the fastest, simplest solution for converting your GIS files into IFF without GIS software - all files processed on your PC for maximum privacy and speed.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as IFF opens on any computer and any phone. reaConverter produces those from GIS in batch, entirely offline.

  • Render every file in a folder to IFF with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.
