Step by step

How It Works

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

Technical note

Before you convert MPR to JXR

MPR carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. JXR 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 JXR 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 JXR opens on any computer and any phone. reaConverter produces those from MPR in batch, entirely offline.

  • Render every file in a folder to JXR 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.

Needed to convert my professional photos to JXR for long-term storage and was pleasantly surprised by reaConverter's handling of this format. The compression maintains exceptional dynamic range while reducing file sizes significantly compared to TIFFs. The batch processing saved me hours of work, and the quality preservation is outstanding - perfect for my HDR photography archive.
