How to use GPX, KML and GeoJSON Converter
Open a GPX, KML, GeoJSON or CSV file (or paste it), choose the output format and download the result.
How it works
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.
Example
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.
