Drop in two or more GPX files to see their elevation profiles on one distance scale. Hover or drag across a chart to read every track at the same point; tap to pin a checkpoint. Files are read in your browser and never uploaded.
Huts, high points and finishes, plus anything you pin on the chart.

Popular routes: track lines © OpenStreetMap contributors (ODbL); elevation from the LINZ NZ 8m Digital Elevation Model (CC BY 4.0). Climbing is worked out the same way for every file: the track is resampled every 10 m and smoothed over about 200 m before counting ascent, so GPS elevation jitter doesn't inflate the total. Figures will differ a little from Strava or AllTrails, which each use their own method. Files stay in your browser and are never uploaded. Save keeps a copy in this browser only; Clear removes it. Export downloads the comparison as a file you can drop back in later. Current design
