TRAVERSE
Start free

Free 3D GPX viewer.

Open a GPX file and see your track on real 3D terrain, with distance, climb and an elevation profile. Free, no sign-in, and the file never leaves your browser.

Your file stays in your browser. Nothing is uploaded. The map tiles come from Mapbox, which sees the area you look at, never your file.

/ How it works

Three steps, no account.

A GPX file is the common language of watches and outdoor apps. If you can export one, you can see it here.

  1. Export a GPX fileGarmin, Strava, Komoot, Suunto, Coros, OsmAnd and most other watches and apps can export an activity or a planned route as a .gpx file.
  2. Drop it inDrag the file onto the viewer above, or choose it from your phone or computer. Nothing is uploaded: your browser reads it.
  3. Read the trackTilt the 3D map, switch between satellite and topo, and move over the elevation profile to see where on the hill each point is.
/ What you see

More than a line on a map.

The numbers use the same elevation rules as the Traverse app, so a track reads the same in both.

Distance and climb

Total distance, climb, descent, highest and lowest point, and the time from the first to the last point when the file has timestamps.

Elevation profile

The whole track as a chart. Move over it and the matching spot lights up on the map.

3D terrain

Your track draped over real elevation at true scale, in satellite or topo, with the map tilted the way you would see the mountain.

Slope angle layer

Where our terrain tiles exist, switch on slope shading from 27° to 45°+. That is Kosovo, Albania and the Sharr range today; elsewhere the viewer still works without it.

/ Questions
What is a GPX file?
GPX (GPS Exchange Format) is a plain text file that stores a track you recorded, a route you planned, or waypoints such as huts and summits. Almost every GPS watch, bike computer and outdoor app can read and write it.
How do I open a GPX file?
Drop it onto the viewer on this page, or press “Choose a file”. On a phone, pick it from your files or downloads. You will see the track on a 3D map with its distance, climb and elevation profile.
Is my GPX file uploaded anywhere?
No. The file is read by your browser and never sent to a server of ours. The map pictures come from Mapbox, so Mapbox can see which area you are looking at, but it never receives your file or its points.
Which files does it support?
GPX files with a track, a route or waypoints, up to 30 MB. FIT, TCX and KML are different formats: export or convert them to GPX first. If a file has no track points the viewer says so instead of showing an empty map.
Why is the climb different from my watch or Strava?
Elevation numbers depend on the source and the smoothing. The viewer uses the elevation stored in your file and ignores changes smaller than 3 m, so GPS noise does not add up to false climb. A watch with a barometer, or an app that corrects elevation from a terrain model, can differ.
Does it work if my file has no elevation?
You still get the track on the 3D map and its distance. There is no climb figure and no profile, because the file has no heights to read.
Does the slope layer tell me whether a route is dangerous?
No. It shows how steep the ground is, where our tiles exist. It describes terrain, not today’s snow or weather, so check local conditions and official bulletins before you go.
Is the GPX viewer free?
Yes. No account and no payment. The Traverse app and map are free too, with an optional Pro plan.
