SVG Optimizer

Optimize and minify SVG files by removing metadata, comments, and default attributes.

What is SVG Optimizer?

SVG (Scalable Vector Graphics) is an XML-based vector image format standardized by the W3C, used for icons, logos, illustrations, and data visualizations because it scales losslessly and is searchable, scriptable, and CSS-styleable. Files exported from design tools like Figma, Illustrator, and Sketch frequently contain editor metadata, hidden layers, redundant transforms, default attributes, and overly precise decimals — bloat that has no visual effect. An SVG optimizer (the canonical implementation is SVGO by Kir Belevich) parses the SVG, applies a configurable plugin pipeline to strip comments, collapse groups, round path coordinates, and minify attribute values, then re-serializes the markup. Typical size reductions are 30–70% with no visual change.

How to use

  1. Paste your SVG code or upload an .svg file.
  2. The optimized version appears automatically with size comparison.
  3. Click Copy to grab the optimized SVG code.

Frequently asked questions

How does SVG optimization work?

It removes unnecessary data like editor metadata, comments, default attribute values, and whitespace — reducing size without changing appearance.

Is it safe to optimize SVGs?

Yes. Only non-visual data is removed: comments, metadata, empty elements, and default values. The visual output stays the same.

Does this tool upload my SVG to a server?

No. Everything runs in your browser using DOMParser and XMLSerializer. Your SVG never leaves your device.

How much can SVG optimization reduce file size?

SVGs from design tools often contain 20-60% unnecessary data. Simple hand-written SVGs may see smaller savings.
