SVG Optimizer

Make an SVG smaller by removing what the editor left behind — comments, editor attributes, empty groups and excess decimal places — without changing a pixel of the picture. Your file never leaves this page. Everything happens in your browser, and there is no upload endpoint to send it to — that is checked by a build gate that fails if any network code reaches a tool’s bundle.

How to do it

1. Open your .svg file in a text editor and paste what is inside it.
2. Choose what to remove. The defaults are the safe ones.
3. Press Copy, and paste it back.

Questions

Will it change how my icon looks?

No. Everything removed is something that cannot change what is drawn — an editor’s comment, a namespace no browser reads, an attribute already set to its default. The two things that look like clutter and are not — viewBox, and ids that something refers to — are kept.

Where does the saving actually come from?

Usually the numbers. An exported path is often written to fifteen decimal places, which is far beyond what any screen can show at any zoom — and it is frequently more than half the file. Three decimals is the default, and you can raise it for a map or a large chart.

Why are ids left alone by default?

Because an id can be referred to from outside the file — by CSS on your page, by a script, or by a in another document — and none of that is visible from here. Removing them is one switch away, with the warning attached.
