Convert GPX to KML
Turn a GPX file from your GPS watch, device or outdoor app into a KML file for Google Earth or Google My Maps. Waypoints, planned routes, and recorded tracks all carry over. Everything runs in your browser, so your file is never uploaded. You can also open your GPX on the MapGridder map, edit it there and export it as KML, GeoJSON or a PDF.
What converts and what is lost
GPX and KML do not describe the same things, so a few fields have no place to land.
| In the GPX | In the KML | Lost |
|---|---|---|
| Waypoint <wpt> | Point placemark with the name and description | Elevation, time, symbol, comment, links |
| Route <rte> | LineString placemark with the route name | Per-point names and elevation |
| Track <trk> | <gx:Track> placemark per segment, with time and elevation on every point, so Google Earth can play it back | Heart rate, cadence, speed and other extensions |
| File metadata and styling | Not written | Author, creation time, colors, custom extensions |
A track with several segments comes out as several playable tracks under the same name.
How to use it
- Choose your .gpx file.
- Open it on the MapGridder map to edit and export, or download the .kml file.
- Open it in Google Earth, import it into Google My Maps, or use any KML viewer.
Frequently asked questions
How do I convert a GPX file to KML?
Choose your .gpx file and download the .kml for Google Earth or Google My Maps, or open the file on the MapGridder map to edit it, add a grid, and export it as KML, GeoJSON or a PDF.
Is my file uploaded anywhere?
No. The conversion runs entirely in your browser, so your GPS data stays on your device. Personal and non-commercial use is free; commercial use needs a paid license.
What is the difference between GPX and KML?
GPX (GPS Exchange Format) is the standard for GPS devices and outdoor apps, storing waypoints, routes, and recorded tracks. KML (Keyhole Markup Language) is the format Google Earth and Google My Maps read. Converting lets you view GPS data in Google's tools.
Need the reverse? Convert KML to GPX. Or open your GPX on the MapGridder map and edit it there. For the full picture, read the GPX and KML guide.
