GPX editor
Reshape any .gpx without leaving your browser. Drag two handles to trim a route
down to the part you want, cut one track into clean segments, or merge several files into one. Your files are
never uploaded.

Files to merge
Private by design
Every edit happens in your browser with JavaScript — your GPX is never sent to any server. Map tiles come from OpenStreetMap; only the map view you see is requested, never your file. Close the tab and your data is gone.
What can you do with it?
Shorten: downloaded a 120 km course but only running the back half? Drag the start and end handles to keep exactly the section you need. Split: turn one long file into separate days or laps — in equal parts, every few kilometres, or at your own break points. Merge: combine several recordings into a single track for a multi-day adventure or a stage race.
Where to get a GPX file
Export one from Garmin Connect, Strava (open an activity → "Export GPX"), Komoot, Wahoo or Coros — or grab a ready-made route from the GPX database.
Frequently asked questions
How do I merge several GPX files into one?
Open the editor, switch to Merge, add your files, drag them into the order you want, and download a single combined track.
Can I trim or crop a GPX file?
Yes. In Shorten mode you drag two handles along the elevation profile to keep only the section you want.
How do I split a GPX track?
In Split mode, click the profile to drop break points, or split into equal parts or every few kilometres, then download each segment.
Is my file uploaded?
No. All editing happens in your browser and nothing is sent anywhere.
