SVG Optimizer
Minify and clean up SVG files right in your browser with SVGO, the industry-standard optimizer. Strip editor cruft, comments and redundant data to shrink the file — while keeping the image pixel-identical and infinitely scalable.
How to use it
- 1Add your SVG
Paste your SVG markup into the input box, or click “Open .svg” to load a file from your device.
- 2Optimize
Click “Optimize SVG”. SVGO runs its default multipass optimization and shows how many bytes it saved.
- 3Copy or download
Copy the optimized markup to your clipboard, or download it as optimized.svg. Your original file is left unchanged.
Why optimize SVG?
SVGs exported from design tools like Illustrator, Figma or Sketch are full of things browsers do not need: XML comments, editor metadata, hidden layers, overly precise decimals and empty groups. That bloat can easily double or triple the file size.
Optimizing removes the waste so your icons and illustrations load faster and your markup stays clean — which matters when an SVG is inlined into HTML or shipped in an icon system. The viewBox is always preserved, so the image keeps scaling crisply at any size.
Runs entirely in your browser
SVGO usually runs on a server or in a build tool. Here it runs as WebAssembly-free JavaScript inside your own browser tab, so your artwork is never uploaded anywhere — you can even work offline once the page has loaded.
Paste your markup or open a .svg file, optimize, then copy the result or download it. The original is never touched.
Frequently asked questions
Are my SVG files uploaded to a server?
No. Optimization happens entirely in your browser with SVGO compiled to JavaScript. Your files never leave your device — you can disconnect from the internet after the page loads and it still works.
Will optimizing change how my SVG looks?
It should look identical. SVGO’s default preset only removes redundant data and rounds needlessly long decimals; the viewBox is preserved so the image still scales perfectly. If you notice any difference, it is usually from removed hidden elements.
How much smaller will my file get?
It depends on the source. Files exported straight from design tools often shrink by 40–70%, while already-minified SVGs may barely change. The tool shows the exact before-and-after size.
Does it keep the viewBox?
Yes. Removing the viewBox is disabled, so your SVG keeps scaling responsively — important for icons and logos that render at many sizes.
