SVG files saved from Illustrator, Inkscape, Figma or Canva are often two or three times bigger than they need to be. This optimiser runs SVGO, the standard open-source SVG optimiser, in your browser: it removes editor data, comments and hidden elements, shortens numbers and paths and merges groups, then shows the new size and both versions side by side so you can check nothing changed.
loading toolHow to optimise an SVG
- Open an SVG file or paste its code.
- Choose the number precision and options, then press Optimise.
- Compare the before and after pictures, then copy or download the smaller SVG.
Good to know
- “Remove width/height” makes an icon scale to whatever box it is placed in.
- Smaller SVGs make pages load faster, which also helps SEO.
Questions
Will the image look different?
With 3 decimals (the default) it looks the same. Fewer decimals make the file smaller but can shift tiny details slightly, so compare the before and after previews.
Why keep ids?
If your CSS or JavaScript points at parts of the SVG by id, tick “Keep ids” so they are not renamed or removed.
Is my code uploaded?
No. The open-source library is downloaded once from a public CDN and then runs in your browser. Your code stays on your device.
Is my data private?
Yes. Everything happens inside your own browser: nothing you type or choose is uploaded to us or anyone else.
Is it free?
Completely free, with no sign-up, no watermark and no limit on how many times you use it. Light ads keep the site running.
