Step by step

How It Works

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

Technical note

How THF and AI differ in practice

AI keeps the geometry as vector paths, so lines and boundaries stay sharp at any zoom, but the map becomes a drawing. Coordinates turn into positions on the page, the attribute table is left behind, and a standard AI records nothing about where on earth the drawing lies. THF carries no styling either, so colours and line weights fall back on defaults rather than matching the map in your GIS.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to AI 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.
