Fewer anchor points, the same shape.

Why a traced SVG has thousands of anchor points, what they cost you, how to cut them down in an editor, and how to start with the few a shape needs.

To reduce anchor points in an SVG, simplify its paths: an editor's Simplify command, such as Inkscape's (Ctrl+L), removes points while almost keeping the shape, and you check the result up close. Fewer points make a lighter file that is easier to edit and to cut. A traced file starts with thousands because the tracer follows every pixel; a file drawn as shapes starts with the few its curves need.

Why so many

Why does a traced SVG have so many anchor points?

Because a tracer follows the pixels it is given. Every step of a jagged edge and every speck of compression becomes points, so a curve a designer would draw with four points comes out with dozens.

The same image, up close, as potrace traces it and as VecSnap draws it, each anchor point shown:

What they cost

Why is my SVG file so big?

Mostly anchor points. Each one is written into the file as numbers, so thousands of them make a file many times heavier than its shapes need, slow every edit, and give a cutting machine more to follow.

How do I reduce anchor points in an existing SVG?

Select the paths and simplify them. In Inkscape, the Simplify command (Ctrl+L) removes anchor points while almost keeping the shape; pressed again within half a second, it simplifies further.

Check the result up close: each point removed lets the curve move a little, so corners soften and circles drift. Simplify the parts that need it, one at a time.

Start with few

Can a file start with few anchor points?

Yes, when it is drawn rather than traced: each edge fitted with the fewest points that keep its shape, and each circle drawn as a circle. The table counts both ways on the same images.

It can. Each point removed lets the curve move a little. Simplify a copy, compare it up close, and keep the version whose corners and circles still match.
