# Tools > Simplify Way

**Reduce the number of nodes in a way, but keep the general shape.**

## Implementation details

After simplification, all of the deleted nodes will be closer than 3 m to the simplified way. In other words, the old and the new way will never be more than 3 m apart.

The tool uses the Ramer–Douglas–Peucker algorithm for way simplification, but makes sure that tagged nodes and nodes with more than one parent way are not deleted.

## Advanced Preferences

You can configure distance between two nodes in the advanced preferences (`simplify-way.max-error`

, in meters, default value is 3). A lower threshold makes the simplification less aggressive.

- SimplifyArea plugin - despite the name, also simplifies ways. Uses a different algorithm and has more parameters for tuning. In particular for nodes A, B, C the node B is not deleted unless
- area of the triangle ABC is lower than 5 m
^{2 } - distance of B to the line AC is lower than 3 m
- angle ABC doesn't deviate more than 10° from 180°

- area of the triangle ABC is lower than 5 m
- Distribute Nodes
