GPX, KML और GeoJSON कन्वर्टर.

Up to 30 MB. Styles, photos and app-specific data (heart rate, cadence) are not converted. Everything is calculated in your browser; nothing you type is uploaded.

Files are parsed in the browser; distances use the haversine formula, elevation gain ignores steps under 1 m and polygon areas are computed on the sphere.

A 4-point morning run in Paris converts from GPX to GeoJSON and measures 4.36 km, +5 m of climbing and 24 min 30 s.
