Online GPX viewer
Maptinker is a free online GPX viewer. Drop in a track from Strava, Garmin, or your phone and see the route on a map, then measure how far it runs. No account, no install, and no tracking cookies.
What is GPX?
GPX is the file your GPS gear speaks. Garmin units, Strava, Komoot, and most phone tracking apps can all export it. It's an XML format with three kinds of thing inside: waypoints (single marked spots), tracks (the breadcrumb trail an activity actually followed), and routes (a planned sequence of points).
Sharing a GPX is easy. Seeing it, without importing it into another app first, is less so. Maptinker draws it on a map in the browser.
How to open a GPX file
- Drag it in. Drop the .gpx onto the map or click to browse.
- See the trail. Waypoints come through as points, tracks and routes as lines, and the map zooms to fit the whole thing.
- Look closer. Click a point or line to read its attributes.
Measure how far a track runs
A common reason to open a GPX is to check the distance of a track. Switch on the measure tool and trace the line to read its length, or measure the area inside a loop. It's the quickest way to answer "how long was that?" without loading the file into a full GPS suite.
You can also:
- Style the tracks by a field and label them.
- Edit attributes or join a CSV of extra data by a key.
- Export to GeoJSON, CSV, a Shapefile ZIP, or FlatGeobuf, so a GPX off your watch can become GeoJSON for a web map in a couple of clicks.
Runs in your browser
The file is read and drawn on your own machine. Nothing to install, no account to create, no tracking cookies, and we never sell or share your data.
