Step by step

How It Works

reaConverter offers the fastest, simplest solution for converting your ZARR files into CGM 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

Not everyone who needs to see ZARR data has GIS software. reaConverter renders it to CGM for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to CGM 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.

We faced a massive challenge: digitizing 20 years of CGM archives into PNG format. Initial estimates projected months of work, but reaConverter's powerful batch processing and resolution scaling let us complete the project in weeks. Most impressively, it handled even our pre-1994 vector files flawlessly—zero errors, perfect fidelity.
