Step by step

How It Works

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

  • Render every file in a folder to JXL 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’s Watch Folders feature has transformed my workflow! I set it to automatically convert my images to JXL, and now every new file I add gets optimized instantly. JXL keeps my photos crisp at half the file size of JPEGs. Super easy setup, flawless results – a must for batch processing!

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.
