Technical note

What changes when you convert GEOJSON to JXL

A GEOJSON file holds geometry and an attribute table, and nothing at all about appearance. Colours, line weights, fills and labels are properties of the GIS project rather than of the file, which is why the same GEOJSON looks different in every program that opens it. The JXL render therefore falls back on defaults and will not match the styled map you see in QGIS or ArcGIS. Expect a clean drawing of the geometry rather than a finished cartographic product. GEOJSON describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the JXL afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.

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 GEOJSON 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!
