SVG Optimizer: Minify & Compress SVG Files
Paste SVG markup and minify with SVGO. Remove comments, metadata, default attributes, and whitespace.

Why optimize SVG?
SVG (Scalable Vector Graphics) are text-based and often include editor metadata, comments, and redundant code. Optimization:
- Reduces file size — smaller downloads.
- Removes editor junk — Illustrator/Figma metadata.
- Strips whitespace — minification like JavaScript.
- Preserves quality — no visual loss, only metadata removed.
What SVGO does
- Removes comments (
). - Strips editor metadata (Illustrator, Figma attributes).
- Removes default attributes (e.g.,
fill="black"if already default). - Minifies whitespace and newlines.
- Simplifies paths where possible.
- Removes hidden layers and unused definitions.
SVG optimization example
Before (editor export):
`xml
`
After (optimized):
`xml
`
Best practices
- Export from design tools — Illustrator, Figma, Sketch.
- Optimize before use — smaller files = faster pages.
- Inspect manually — ensure important paths aren't lost.
- Use inline SVG — embed SVG directly in HTML for styles.
Frequently asked questions
Does optimization affect visual appearance?
No, optimized SVGs look identical. Only metadata and whitespace are removed.
Can I undo optimization?
Save the original. Optimization is lossy for metadata but preserves vector data.
Should I minify SVG for production?
Yes, especially for large icons or illustrations. Minified SVGs load faster.
