KML to GPX

KML is the format of Google Earth and Google Maps, GPX that of GPS devices and outdoor apps (Garmin, Komoot, Wahoo). To get a route drawn in Google Earth onto a bike computer or hiking GPS you would otherwise have to chain two tools. This tool does it in one step: KML in, GPX out.

Placemarks (Point) become waypoints (wpt), lines (LineString) become tracks, compound lines (MultiGeometry) become multi-segment tracks. An area (Polygon) is output by GPX as a closed track, since it has no area format. Names are kept, elevation is carried over as ele. The coordinate order is correctly reordered from KML (longitude, latitude) to the GPX attributes lat/lon.

Everything runs entirely locally in the browser - your possibly sensitive route and location data never leaves your device. Honestly framed: geometry, name and elevation are transferred. KML-specific presentation (styles, icons, tours, overlays) has no counterpart in GPX and is not carried over. A KML file without placemarks, or an invalid file, is rejected with a clear message.

Specifications

In 3 steps

1. Drop your KML file.
2. The conversion runs automatically.
3. Download the GPX (for your GPS device).

Limitations: Converts KML straight to GPX 1.1 (internally via the GeoJSON model): Point to wpt, LineString/MultiGeometry to trk, Polygon as a closed track (GPX has no areas). Name and elevation are kept. KML styling, tours, overlays and any KML timestamp (TimeStamp/TimeSpan) are not carried over - this conversion only reads name, description and geometry per placemark. Coordinates WGS84, correctly reordered to lat/lon. KML without placemarks or invalid KML is rejected with an error.
