Simplify a GPX file and reduce points
Oversized GPX files import badly and make navigation stutter. Reduce the point count at your chosen precision — the route shape stays, the file shrinks.

HOW IT WORKS
How to simplify a GPX file
- 01
Import the GPX
Load the large GPX file into the editor.
- 02
Set the simplification tolerance
In the Edit panel choose Simplify and a tolerance of 5, 10 or 20 metres. A notice shows the point count before and after.
- 03
Compare and export
Check the point count and deviation, then download the smaller GPX.
Frequently asked questions
Will simplifying ruin the route shape?+
No, at a sensible level. The algorithm (RDP) drops redundant points while keeping the characteristic bends.
Why does my device reject a big GPX?+
Watches and bike computers cap the number of points per route. Simplifying helps you stay under that limit.
Can I see the before and after?+
Yes, the editor shows the point count before and after, so you stay in control of the change.
