GPX is the format of GPS devices and outdoor apps (Garmin, Komoot, Strava, Wahoo), KML that of Google Earth and Google Maps. To view, share or drape a recorded tour or track over the satellite imagery in Google Earth, you need it as KML. This tool does it in one step: GPX in, KML out.
Waypoints (wpt) become placemarks (Point), routes (rte) and tracks (trk) become lines (LineString); a track with several segments becomes a compound geometry. Names are kept, elevation values (ele) are carried over as the third coordinate. The coordinate order is correctly reordered from the GPX attributes lat/lon to the KML order longitude, latitude.
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. GPX extensions such as heart rate, cadence or timestamps have no counterpart in plain KML and are not carried over. A GPX file without usable points, or an invalid file, is rejected with a clear message.

Limitations: Converts GPX straight to KML 2.2 (internally via the GeoJSON model): wpt to Point, rte/trk to LineString, a multi-part track to MultiGeometry. Name and elevation are kept. GPX extensions (heart rate, cadence, timestamps) are not carried over. Coordinates WGS84, correctly reordered to longitude, latitude. GPX without usable points or invalid GPX is rejected with an error.
This lets you view a recorded tour in Google Earth in one step, without a detour via an intermediate format - ideal for viewing, sharing or draping over the satellite imagery.
Routes and tracks become lines; a track with several segments becomes a compound geometry (MultiGeometry).
No. These GPX extensions have no counterpart in plain KML; geometry, name and elevation are transferred.
No, the conversion happens entirely locally in the browser; route data never leaves your device.
