Does this upload my GPS track?

No. The GPX is parsed in your browser using the built-in XML parser and drawn locally — none of your coordinates are sent to a server.

Why is the map a line drawing rather than satellite tiles?

To stay fully offline and key-free, the track is rendered as a scaled SVG path inside its bounding box rather than over external map tiles. The shape, scale and elevation are accurate.

What GPX elements does it read?

It reads track points (trkpt) across all track segments, plus standalone waypoints (wpt). Latitude, longitude and elevation (ele) attributes are all parsed.

How is the distance calculated?

Distance is the sum of great-circle (Haversine) distances between consecutive track points, which is accurate for the short hops typical of GPS logs.

Does it handle multiple tracks or segments?

Yes. All segments of all tracks are read in order and concatenated into one continuous path for display and distance totals.

GPX Viewer — Gera Tools

View a GPX file in your browser

This tool loads a GPX file — the standard format exported by Garmin, Strava, Komoot and most GPS apps — and plots the route as a scaled track map with an elevation profile and summary stats. It is built for hikers, cyclists and runners who want a quick look at a recorded route without signing into a fitness platform.

How it works

The GPX file is XML, so the tool parses it with the browser’s built-in DOMParser. It collects every trkpt (track point) across all trkseg segments and all trk tracks, reading the lat and lon attributes and the optional ele (elevation) child. The latitude/longitude pairs define a bounding box; the path is then projected into that box and drawn as an SVG polyline so the shape stays accurate at any size. Total distance is the running sum of Haversine great-circle distances between consecutive points, and the elevation values are charted as a profile beneath the map.

Notes

Everything runs locally — your track is never uploaded. The view is deliberately key-free and tile-free so it works offline and keeps your location data private. For ascent/descent totals and pace, see the GPX Elevation & Distance Stats tool.
