GPX Viewer
View a GPX track's route shape, total distance, and elevation gain/loss from an uploaded .gpx file. Runs entirely in your browser.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
A sample track is shown below — upload your own .gpx file to replace it.

How it works
- Upload a .gpx file exported from a GPS watch, phone app, or route planner.
- See a scaled route outline plus total distance, points, and elevation gain/loss.
The formula
Distance between two points (haversine):
a = sin²(Δlat/2) + cos(lat1)·cos(lat2)·sin²(Δlon/2)
d = 2 · R · asin(√a), where R ≈ 6,371,000 m
FAQ
What GPX elements does this read?
Track points (<trkpt>), route points (<rtept>), and waypoints (<wpt>), including their latitude, longitude, and optional elevation (<ele>) — the standard fields nearly every GPX exporter includes.
How is distance calculated?
The haversine formula sums the great-circle distance between each consecutive pair of points, using Earth's mean radius — the same approach GPS devices and running apps use for straight-line-between-points distance.
Why is the route plot not on a real map?
The plot is a simple SVG line scaled to your track's own latitude/longitude bounds — it shows the route's shape without loading a third-party map tile service, keeping the tool fully offline and private.
Is my GPX file uploaded anywhere?
No — the file is parsed and read entirely in your browser. Nothing is sent to a server.
How we compare
