Select GeoJSON Features Online

Upload a GeoJSON file, click features on the map to select them, then download just your selection in any format.

All processing happens in your browser. Your files never leave your device.

GeoJSON is the natural choice when your selected features will be used in a web map, JavaScript pipeline, or any tool that reads GeoJSON natively — the result is a single UTF-8 text file with no dependencies.
