TCX to KML
Convert TCX to KML online, free and without signing up. Drop in the TCX file or paste its text, and save the KML file. Names and positions carry across. Nothing is uploaded: your browser reads and writes the file on your device.
How to convert TCX to KML
- 1Drop your TCX file in, or click to choose it
- 2Check the drawing and the notes on what carries over
- 3Save the KML file
- A KML file, named like the one you dropped in.
What happens to your files
- Nothing is uploaded.Your TCX file is read and the KML file is written by your browser, on your own device.
- No map tiles are loaded.The preview is a flat drawing of the file, so no location is sent anywhere.
- You see what is lost.Every file has notes on what KML could not keep.
What you can do
- Convert TCX to KML with one tool. You see a drawing of the points, lines and areas in the file, and the KML text, before you save.
- Drop several files at once and save each one, or all of them together.
- Paste the text of a file instead of dropping it. GeoJSON, KML, GPX, WKT and CSV are recognised.
- Get a note for everything the KML format cannot hold, such as areas in GPX or heart rate in KML, so nothing disappears quietly.
Good to know
- TCX is Garmin's XML format for workouts, with positions, time, heart rate and cadence per point. It needs a time on every point to be written.
- KML is the XML format of Google Earth for places, paths and areas, with names and descriptions. It has no place for heart rate, cadence or power.
- Only longitude and latitude (WGS 84, EPSG:4326) are read. A file in another coordinate system is refused with a message to reproject it first.
- The tool writes GPX, KML, GeoJSON and CSV. GPX has no areas, so they are saved as closed tracks, and holes inside areas are left out.
- A CSV is read by its latitude and longitude columns. You choose whether its rows are separate points or one track.
- A file without a single point, line or area is not converted, and the page says what it found instead.
Questions
Is TCX to KML free, and is my file uploaded?
It is free, and there is no sign-up. The file is not uploaded: your browser does the conversion on your device.
Do names, elevation and times stay?
They carry across wherever the KML format has a place for them. What does not fit is listed under the drawing before you save.
Can I convert several files at once?
Yes. Drop them together. Each gets its own card and its own save button, and "Save all" saves them in one go.
Does it work with a track from my GPS watch or phone?
Yes, when it is a GPX, TCX, FIT or KML file, or a CSV with latitude and longitude. The result is a normal KML file you can open elsewhere.
