Drop a GPX file (or FIT, TCX, KML/KMZ, GeoJSON) and get an instant elevation profile of the whole track, plus total ascent, descent and the min/max altitude. Move your mouse along the chart to read distance and height at each point.
FAQ
How is ascent calculated?
Total ascent and descent are summed with a small 3-metre threshold to filter GPS noise.
Does my file leave my device?
GPX is processed in your browser; other formats are only converted, never stored.
