Edit GPX track points
One stray point in the wrong spot, a wrong elevation, or a bad timestamp can spoil a whole track. Open your file, step to the exact point, and fix its coordinates, elevation, time or name — or insert and delete points — one at a time, with full undo.
Open the tool
Opens the GPX editor with the edit gpx track points tool selected. Your file stays on your device — nothing is uploaded.
Open the GPX point editorHow to edit gpx track points
- Open your file. Drop a GPX into the precision editor (Points) — it's read locally, never uploaded. Point editing needs GPX, which preserves structure.
- Step to the point. Use the slider or the ‹ › buttons to select a point; its latitude, longitude, elevation, time and name appear in editable fields.
- Edit, insert or delete. Change a field and Apply, Insert a point after the current one, or Delete it. Invalid coordinates are rejected; every change is undoable.
Formats & what's kept
- Input: GPX (FIT/TCX/KML/KMZ can be trimmed but not point-edited)
- Output: GPX 1.1
- Preserved: Every other point, the multi-track/segment structure, waypoints, routes, sensors and unknown extensions. Edits are addressed by a stable id, so your selection survives insertions and deletions elsewhere.
- Changed or dropped: Nothing beyond the point you change or delete. Latitude/longitude out of range and non-finite values are rejected rather than written.
A real example
A tunnel left one point 200 m off the road. Step to it, correct its latitude and longitude to sit back on the line, and the track's distance and speed recompute — without disturbing the thousands of good points around it.
| Before | After |
|---|---|
| point 1,412: 47.401, 8.500 (off-road) | point 1,412: 47.398, 8.512 (on the road) |
Try it yourself with a free sample GPX file — the numbers above are illustrative of a typical case.
Privacy
This edit runs entirely in your browser using the W3C File API — your file is never uploaded, and your original is left untouched (the editor works on a copy). This tool makes no network requests at all to do its job; only route planning and snapping, which this tool doesn't perform, would ever send coordinates to a routing provider.
Frequently asked questions
Why does point editing require a GPX file?
Editing individual points safely means preserving the file's structure — segments, waypoints, routes and extensions. That's the lossless GPX document model; FIT, TCX and KML are flattened on import, so they can be trimmed but not point-edited here.
Can I edit many points at once?
This tool edits one point at a time with validation. For bulk changes — trimming a range, removing spikes, smoothing elevation — use the matching editor or repair tool, which act on many points in one step.
Does my selection move when I insert or delete a point?
Your selected point keeps its identity even after you add or remove points elsewhere, because selection is tracked by a stable id rather than a position that would otherwise drift.
Is a bad coordinate rejected?
Yes. A latitude outside −90…90, a longitude outside −180…180, or a non-numeric elevation or unparseable time is refused with an inline message, so you can't write an invalid point.
