Step by step

How It Works

reaConverter offers the fastest, simplest solution for converting your ARC files into STP 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 STP opens on any computer and any phone. reaConverter produces those from ARC in batch, entirely offline.

  • Render every file in a folder to STP 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.

reaConverter handles STP file conversion excellently. The batch processing feature is perfect for converting multiple CAD files at once, and the drag-and-drop interface makes it super easy to use. Quality is preserved well during conversion, and it supports plenty of output formats. Recommended for engineers and designers.
