Convert FIT to GPX
Turn a FIT file from a Garmin, Wahoo or Coros device into a GPX — with heart rate and cadence preserved.
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.

FIT in, GPX out
FIT is the native binary format of most bike computers and watches. Open a .fit file here and it’s decoded to GPX in your browser: records become track points, laps become segments, course points become waypoints. Nothing is uploaded.
How to convert fit to gpx
- Open your .fit file (or drag it onto the map).
- Optionally edit the track.
- Download GPX.
FAQ
Is my FIT file uploaded to a server?
