Convert NetCDF to GeoJSON — free and private
Drop a .nc file, pick a variable with latitude/longitude dimensions, slice the time or level you need, and download GeoJSON for QGIS, Leaflet or Mapbox. No Python, no upload — the conversion runs entirely in your browser.
Why convert NetCDF to GeoJSON here
Turn gridded climate and ocean data into map-ready features.
No Python required
Skip netCDF4, xarray and GDAL scripts. No conda environment, no compiler — just drop the file and download GeoJSON.
Stays on your machine
The file is decoded locally and never uploaded, so confidential or unpublished model output is safe.
Map-ready output
GeoJSON point features with values, ready to drop into QGIS, Leaflet, Mapbox or any GIS workflow.
Geographic-aware
GeoJSON is enabled only when the variable has latitude/longitude dimensions, so coordinates are always correct.
