    FAQ

    How do I convert KML to GeoJSON?
    Upload the KML file in the tool above and a summary of its contents appears (points/lines/polygons and attributes). Pick the coordinate system if the file carries none, then hit “Convert & download” — the GeoJSON file saves straight to your device.
    Is my file uploaded to a server?
    No — everything runs inside your browser and the file never leaves your device. No sign-up, no usage caps.
    Are attributes, names and elevations preserved?
    Yes, as far as GeoJSON allows: names and Z values always pass through, and attribute fields carry over wherever the format has a table — any potential loss is shown explicitly before converting; nothing is dropped silently.

    All formats and directions (8 formats in and out) live in the full surveying file format converter.
