SVG Optimizer

Minify SVG markup with SVGO.Design & Color

SVG Optimizer

Minify SVG markup with SVGO (loaded on demand): metadata, editor cruft and path precision are reduced without visual change.

About this tool

SVGO — the optimiser behind most build pipelines — runs on demand: editor metadata, hidden cruft and excessive path precision are reduced while the picture stays identical.

How to use the SVG Optimizer tool

  1. Paste the SVG. Exported from any editor.
  2. Optimise. SVGO loads on demand and runs multipass.
  3. Compare and download. Byte counts before and after are shown.

Supported formats

Input

  • Plain text or file input

Output

  • Converted or analysed output

Inputs are validated before anything is processed. Invalid values and unsupported files are rejected with a clear error instead of failing silently.

Frequently asked questions

Is the image unchanged?

Visually yes; the markup is restructured with multipass mode on.

What gets removed?

Editor metadata, comments, empty groups, redundant precision.

Why is my file already small?

Optimised sources have little to lose — the tool says so honestly.
