How to reduce svg path complexity with the ramer–douglas–peucker algorithm
- Step 1Upload your SVG — Drop an SVG with complex paths — typically from auto-tracing a raster image, or pen-tool illustrations with high node density.
- Step 2Set the tolerance — Start at 0.5 for minimal change. Try 1.0 for noticeable simplification with low quality loss. Use 2.0+ only for shapes where approximation is acceptable.
- Step 3Download the simplified SVG — Compare the before/after node count and file size. Download the simplified version. Combine with the Precision Tuner for further file size savings.
Frequently asked questions
What tolerance value should I use?+
0.5 for minimal visible change, 1.0–2.0 for icon simplification, 3.0+ only for rough shapes. Always preview the result at your intended display size before committing.
Does this affect Bézier curves?+
The tool converts cubic Bézier segments to polylines, applies RDP, then converts back to smooth curves. Some curve smoothness is traded for fewer control points.
Is this the same as SVGO's path plugins?+
SVGO's convertPathData shortens number representations; it doesn't remove control points. RDP path simplification actually removes unnecessary nodes — a different and more aggressive optimisation.
Can I undo simplification if it looks wrong?+
The original file is never modified. If the simplified result looks wrong, increase the tolerance value or adjust the preview. The tool shows a diff overlay to compare.
