A GPX editor in your browser

Click the map to set a start, then waypoints: the line follows trails or roads for the mode you pick (hiking, running, road cycling, gravel, MTB or straight line). Distance, elevation gain and time update with every point, and the GPX file downloads with no account and no email address.

The editor also opens an existing GPX file: the track appears with its profile, can be extended from the map, and becomes editable point by point.

How to create a GPX file online

1. Set the start
Search for a town or place in the field at the top of the panel, or pan the map, then click (or tap) where you start. The mode, top left of the panel, sets the network the line follows.
2. Add waypoints
Each click adds a waypoint, joined to the previous one along the paths on the map. Drag a point to move it, drag the line to insert a point, Alt + click for a straight line.
3. Export the GPX
“Export GPX” downloads a GPX 1.1 file with elevation, ready for Garmin Connect, the Suunto app, Komoot and most hiking apps.

Edit an existing GPX file

“Open a GPX file” loads a file from your computer or phone. The imported track appears as it is, with its distance, elevation gain and profile. A click on the map extends it; “Make editable” turns it into waypoints you can move, delete or reorder.

The toolbar buttons reverse the direction, close the loop back to the start, and undo or redo every change (Ctrl + Z and Ctrl + Shift + Z, or Cmd on a Mac). The route name, at the top of the panel, becomes the name of the exported file.

Distance, elevation gain and time: how they are worked out

Distance follows the surface of the Earth point by point (haversine formula). Elevation gain is computed on elevations averaged over 100 m, and a climb or a descent only counts once it exceeds 5 m, so small wobbles in the terrain and in elevation models do not inflate the total. It is the same calculation as the GPX Path app for Mac, to the metre.

Elevations come from the BRouter routing service for sections that follow paths, from the IGN RGE ALTI model in France for straight lines and files imported without elevation, and from Terrain Tiles (SRTM and national models) elsewhere.

Time is an estimate per mode: 4.5 km/h on the flat for hiking, plus 1 h per 350 m of climbing and 1 h per 700 m of descent; for running, the effort kilometre (1 extra km per 100 m of climbing) at 10 km/h; for cycling, a flat speed for the bike plus climbing time.

What stays on your device

The file you open is read by your browser and is not sent to any server. The route in progress is kept in your browser’s local storage, so you find it again on your next visit.

To follow paths and provide elevations, the editor only sends the coordinates of the points involved to the routing service (BRouter) and the elevation services (IGN, Terrain Tiles); place search sends the text you type to Photon. Each service is described in the privacy policy.

Frequently asked questions

Is the GPX editor free?

Yes. It runs in your browser, with no account, no email address and no limit on the number of routes. The GPX export is immediate.

Can I edit an existing GPX file?

Yes. “Open a GPX file” shows the track with its profile. You can extend it, then “Make editable” turns it into waypoints you can move or delete before exporting again.

Is my route saved?

It is kept in your browser, on this device. “Copy link” gives an address that holds the route’s waypoints: whoever opens it gets the same route, recalculated.

Why is the elevation gain different from my watch?

Every tool smooths elevation its own way, and a watch measures with its barometer. Here, elevations are averaged over 100 m and a climb only counts once it exceeds 5 m. A gap of a few per cent is normal.

Will the GPX work on my watch?

The exported file is a standard GPX 1.1 with elevation. Garmin Connect, the Suunto app and Komoot import it as a course or route, then send it to the watch or phone.
