FIT / TCX → GPX converter
Convert any watch or bike-computer activity file to GPX. Heart rate, cadence and power are preserved in standard GPX extensions. Everything runs locally — nothing is uploaded.

.fit · .tcx · .gpx · stays on your device
Which devices work?
Any device or app that exports .fit or .tcx: Garmin watches/Edge computers, Wahoo ELEMNT, Polar, Suunto, Apple Watch (via Health export), and apps like Strava, Komoot and Zwift. You can also re-convert an existing GPX file.
Is my data uploaded?
No. All parsing and conversion happens entirely in your browser. Your activity file never leaves your device.
What data is preserved?
GPS coordinates, elevation, timestamps, speed, heart rate, cadence and power are written to the GPX output using standard Garmin TrackPointExtension fields, so any GPX-aware tool can read them.
