What is GPX?
GPX (GPS Exchange Format) is the universal, human-readable XML standard for GPS tracks — understood by almost every map, route planner, watch and hiking site.
What is TCX?
TCX (Training Center XML) is Garmin's training format — like GPX but with extra workout data such as heart rate and laps.
Why convert GPX to TCX?
Some Garmin devices and training tools import TCX rather than GPX. Convert your GPX track to TCX to load it there.
How to convert GPX to TCX
1. Drop your GPX file above (or click to choose). 2. It is converted on the spot. 3. Your TCX download starts automatically. No sign-up, and your file is never stored.
FAQ
What happens to my file?
Your file is sent to the Reisezoom server for processing, handled there and deleted immediately — nothing is stored. A browser cannot read FIT, TCX, KML or KMZ — some of those are packed binary formats. The conversion uses the same component as the desktop app.
Is it free, no sign-up?
Yes — completely free, no sign-up, and your file is never stored; it is only used to convert.
Will it work on my Garmin?
TCX is Garmin's own training format, so it loads on most Garmin devices and Garmin Connect.
