How to use the SVG Optimizer

  1. Paste SVG code or open an SVG file.
  2. Adjust decimals and options such as keeping the viewBox or IDs.
  3. Compare the previews, then copy or download the optimized SVG.

Frequently asked questions

How much smaller will my SVG get?

Files exported from design tools often shrink by 30-70%.

Why keep the viewBox?

The viewBox lets the SVG scale with CSS. Removing it can break responsive sizing.

Is my file uploaded?

No. SVGO runs in your browser.
