Manual MPR to JXL conversion wastes hours. reaConverter automates the process — just add files and click Convert. Everything happens offline on your computer. No uploads, no cloud risks. No command line and no scripting, unlike the usual ogr2ogr route.

Step by step

How It Works

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

Technical note

How MPR and JXL differ in practice

MPR carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. JXL has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the MPR original if the data still has to go back into a GIS. MPR stores pixels without compression loss and JXL does not, so this is a one-way step. Choose a high quality setting, and avoid converting the same file back and forth, because each pass compounds the artefacts.

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 MPR 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.
