You found a great route but want to start from the other end? Just reversing the point order breaks most files: the clock suddenly runs backwards, and analysis tools refuse the track. This tool flips the direction and mirrors the timestamps — the new first point starts at the original start time and the gaps between points are preserved in reverse order, so duration and pace stay plausible.
FAQ
What happens to my file?
Your file is sent to the Reisezoom server for processing, handled there and deleted immediately — nothing is stored. So that the web tool and the desktop app arrive at the same number, both use the same component — and that one runs on the server.
Why not just reverse the points?
Because then the last timestamp comes first and time runs backwards. Many apps silently drop such files. Mirroring keeps a forward-running clock.
Do elevation and distance change?
The distance stays identical. Ascent and descent swap — what was a climb is now a descent, which is exactly what you want to know.
Does this plan a new route?
No. This flips an existing track. This site deliberately does no route planning — it refines tracks you already have.
What about waypoints?
Track points are reversed; the file stays standard GPX, so waypoints stored alongside are kept by format converters.
