Step by step

How It Works

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

Technical note

How THF and GIF differ in practice

A THF file holds geometry and an attribute table, and nothing at all about appearance. Colours, line weights, fills and labels are properties of the GIS project rather than of the file, which is why the same THF looks different in every program that opens it. The GIF render therefore falls back on defaults and will not match the styled map you see in QGIS or ArcGIS. Expect a clean drawing of the geometry rather than a finished cartographic product. THF describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the GIF afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to GIF with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Stamp a text watermark, such as a project name or a date, on every image
  • 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.

Working in a print studio means constantly juggling obscure file formats. I used to waste hours Googling converters or installing random software — until reaConverter became my Swiss Army knife. Install it once, and you're set forever. No internet? No problem!
