How It Works

Conversion Mechanics

GPX is the standard export format for GPS tracks and waypoints from fitness watches, hiking apps like AllTrails or Strava, and dedicated GPS units, but showing that track on a web map usually means GeoJSON. This converts GPX track points, routes, and waypoints — including elevation and timestamps where present — into GeoJSON features you can load directly into Leaflet, Mapbox, or MapLibre.

Why It's Private

Runs Entirely In Your Browser: Files are decoded and re-encoded strictly in local memory.
No Network Requests: The converter makes no calls to any server — check your browser's DevTools Network tab to confirm.
Nothing to Sign Up For: No account, no upload, and no server-side storage of your files.
Runs On Your Hardware: Processing uses your own device's CPU via Web Workers, not a remote server.
