# Minify

> Reduce the number of GPS points while preserving route shape

The Minify tool reduces the number of GPS points in a track while maintaining the overall shape and accuracy of the route. This is useful for decreasing file size and improving performance.

## How It Works

The tool uses the [Ramer-Douglas-Peucker algorithm](https://en.wikipedia.org/wiki/Ramer%E2%80%93Douglas%E2%80%93Peucker_algorithm) to intelligently remove points that don't significantly contribute to the route's shape.

## Using the Tool

1. Select a track in the [File Tree](/docs/app/file-tree)
2. Open the Minify tool
3. Adjust the **tolerance slider** to control simplification level
4. Preview the simplified track on the map
5. Review the point count showing how many points will be kept
6. Click **Apply** when satisfied

## Tolerance Setting

The tolerance value represents the maximum distance allowed between the original track and the simplified version.

* **Lower tolerance** → More points kept, closer to original
* **Higher tolerance** → Fewer points, more simplified

<Note>
  The tolerance is measured in meters. A tolerance of 5m means no point on the simplified track will be more than 5 meters away from the original path.
</Note>

## Use Cases

* **Large GPS recordings** - Reduce file size for tracks with excessive point density
* **Device compatibility** - Some GPS devices have limits on the number of points they can handle
* **Faster loading** - Simplified tracks render more quickly on the map
* **Sharing** - Smaller files are easier to share and upload
