Anonymize a GPX file
Before you share a track: remove the first and last metres around your front door and delete the timestamps. Then the file reveals neither where you live nor when you were out.
Everything runs in your browser. Nothing is uploaded.

How to anonymize a GPX file
- Open the GPX file. Track and elevation profile show up at once.
- Choose a radius under Privacy zone (e.g. 300 m) and tap “Apply privacy zone”: every point within that radius of the start and finish is removed. Then tap “Remove timestamps”.
- Check on the map that the start and finish are no longer at your home, then download the file.
What does a GPX file reveal?
- Start and finish – for loops from your door, your address.
- Timestamps – date, time and your pace.
- Some devices also store heart rate and the device name.
The privacy zone cuts the track at the start and end until it leaves the chosen radius. 200–500 m is usually enough; in sparsely populated areas choose more.
Frequently asked questions
Is my file uploaded?
No. The file is processed entirely in your browser and never leaves your device.
Which radius makes sense?
In a town 200–300 m is enough; in the countryside rather 500 m to 1 km, because fewer houses are nearby.
Can I delete only the times and keep the track?
Yes. Just tap “Remove timestamps” and download the file – the route stays complete.
