SVG Optimizer

Paste your SVG code and get an optimized version powered by SVGO. The tool removes unnecessary metadata, whitespace, and redundant attributes while preserving visual fidelity. See the file size savings at a glance. Everything runs locally in your browser.

What SVG optimization does and why it's worth it

SVGs exported from Illustrator, Figma, or Sketch are full of data the browser never needs: editor metadata, comments, XML declarations, unused IDs, and coordinates carried out to absurd decimal precision. This tool runs SVGO — the industry-standard optimizer — to strip all of that while keeping the rendered image pixel-identical. Real-world savings of 30–70% are common, and they add up fast when SVGs are inlined into your HTML.

Smaller SVGs mean less markup to download and parse, which helps page weight and Largest Contentful Paint — part of Core Web Vitals. Everything runs in your browser; nothing is uploaded.

How to use it

Paste your SVG markup into the input.
Read the optimized output and the before/after size savings.
If you target elements by ID or class in CSS/JS, confirm those survived the cleanup.
Copy the result and use it inline or save it as a file.

Frequently asked questions

What does SVG optimization actually remove?

SVGO strips data that doesn't affect rendering: editor metadata (Illustrator/Figma comments), XML declarations, unused IDs and namespaces, excessive decimal precision on coordinates, hidden elements, and redundant attributes. The visible image stays identical while the file gets noticeably smaller.

Is SVG optimization lossless?

For the visible result, effectively yes — default settings preserve appearance. The one thing to watch is coordinate precision: aggressive rounding can very slightly shift complex paths. The defaults here keep enough precision that you won't see a difference in normal use.

Will optimizing break my CSS or JavaScript hooks?

It can if you target elements by ID or class, because cleanup can remove or rename unused ones. If you animate or style the SVG via specific IDs/classes, keep those — paste the optimized output back into a quick test to confirm your hooks still work.

Why is a smaller SVG good for SEO and performance?

Smaller SVGs download and render faster, which helps Largest Contentful Paint and overall page weight — both factor into Core Web Vitals. Inline SVGs especially benefit, since the markup ships inside your HTML on every page load.

Are my files sent to a server?

No. Optimization runs in your browser with SVGO compiled to run client-side. Your SVG is never uploaded or stored.
