Drop a GPX file (or FIT, TCX, KML/KMZ, GeoJSON, NMEA) and it appears on an interactive OpenStreetMap with start and finish markers, an elevation profile linked to the map, and your key tour data. Nothing is uploaded for GPX — it is read directly in your browser.
FAQ
Which files can I view?
GPX directly in your browser; FIT, TCX, KML/KMZ, GeoJSON and NMEA are converted on the fly.
Is my file stored?
No. GPX is read locally in your browser; other formats are only converted, never stored.
