FAQ

Will simplifying change my distance/elevation gain?

Simplifying reduces point count, which can slightly change calculated distance and elevation gain in some apps. Use a lighter tolerance if you want to preserve fine detail.

Which setting should I pick?

Light is a good default for GPS noise cleanup. Medium/Strong are better for sharing or size limits, but can cut corners.

Why does my GPX get much smaller?

Many GPX files store thousands of points. Removing redundant points reduces file size and often improves performance in some devices.
