Convert TCX to GPX
Turn a Garmin TCX export into a clean GPX file — heart rate and cadence come along for the ride.
Drag a file anywhere onto the editor, or .
Nothing is uploaded — editing happens in your browser. Reads .gpx, .tcx, .fit, .kml and .kmz.
Fix GPS errors
Your watch drifted or teleported? Remove spikes that jump away and snap back.
Reduce points
Fewer points = a smaller file that fits your device's course limit. Re-run anytime — it always starts from your full track, so you can go up or down.
Advanced: spacing & simplify
Edit points
Elevation
This file has no elevation data.
Opt-in: sends only the coordinates of points needing elevation to the terrain provider. Your file is not uploaded.
Re-upload as new
Strava & Garmin reject re-uploads as duplicates. Shift the time or randomize the file ID so it uploads as new.
Plan a route
Click the map to drop points. Below zoom 12 the first click zooms in so you can place accurately.

TCX in, GPX out
TCX is what Garmin Connect exports for some activities. Open it here and it’s converted to GPX instantly; each lap becomes a track segment and any course points become waypoints. Then edit or download.
