This free GPX viewer opens any GPX file — from a Garmin, a watch, a phone app, or a
route planner — and shows its tracks, routes, and waypoints on a map with full
statistics and interactive elevation, heart rate, and speed charts. Tracks are colored
by climbing effort or by elevation, and hovering a chart pinpoints that exact spot on
the map. Everything runs in your browser: the file is never uploaded.
How do I view a GPX file online?
Drag the file onto the page (it lands in the panel on the right), or press
Load GPX and pick it (Ctrl+O / Cmd+O). The map zooms to your data and
the panel lists every track segment, route, and waypoint — click any of them to zoom
in and highlight it.
Is my GPX file uploaded to a server?
No. The file is parsed entirely in your browser and never leaves your computer —
nothing is uploaded or stored. That makes the viewer safe for private tracks and
fast even for large files.
What statistics does it show?
Total distance, duration and moving time, elevation gain and loss, minimum and maximum
elevation, average and maximum speed (when the file has timestamps), average and
maximum heart rate, power and cadence (when the device recorded them), plus
per-segment distances and point counts.
Can I see heart rate and speed charts?
Yes. Under the map, pick Elevation, Heart rate, Speed, or any other series the file
carries (power, cadence, temperature). Heart rate comes from the Garmin and Apple
Health extensions that watches write; speed is worked out from the timestamps over a
few seconds, so GPS jitter and stops do not spike it. Hover the chart to follow the
spot on the map.
What do the track colors mean?
In Effort mode the track is colored by grade — green for flat, orange and red for
climbs, blues and purple for descents — so you can read the character of a route at
a glance. Switch to Elevation mode to color by altitude instead.
Can I edit or convert my GPX file?
You can re-export the loaded data with Export GPX. To draw or edit geodata, try the
GeoJSON Editor; to plot plain coordinate lists, use
Plot Points.
Is there an app?
Yes. GPX Explore, on iPhone, iPad and Mac, opens any GPX file with the track coloured by grade, every sensor charted and a workout summary. Free.
