What exactly gets reversed?

The order of every track point across all segments is flipped, and waypoints are reversed too, so the final point of the original route becomes the first point of the reversed one.

What happens to timestamps?

By default the original times are kept on each point, which leaves them out of order. Enable the re-time option to rewrite timestamps so they increase from a fresh start time, matching the new direction.

Is elevation preserved?

Yes. Each point keeps its ele value, so a reversed climb correctly becomes a descent and vice versa in any tool that reads the file.

Does this work for out-and-back routes?

Yes — that is the main use case. Reverse the outbound leg to get a ready-made return route without re-recording it.

Is my route uploaded?

No. The file is parsed and reversed entirely in your browser using the built-in XML parser, so your GPS data never leaves your machine.

GPX Route Reverser — Gera Tools

Reverse a GPX route in your browser

This tool flips a GPX route so you can follow it in the opposite direction — the classic case being an out-and-back walk or ride where you want a clean return file. It is built for anyone who recorded a one-way track and needs the reverse without re-walking it.

How it works

The GPX is parsed with the browser’s DOMParser and all trkpt track points are collected in order, then the order is reversed so the last point becomes the first. Waypoints are reversed too. Each point keeps its lat, lon and ele, so elevation naturally flips from climb to descent. Because reversing leaves the original time stamps out of order, an optional re-time mode rewrites the timestamps so they increase from a start time you choose, preserving the spacing between consecutive points so the moving profile still makes sense.

Notes

Everything runs locally — nothing is uploaded. If you only need to follow the route on a map, plain reversal is enough; enable re-timing only when your device or app insists on monotonic timestamps.
