SVG Minifier

Shrink SVG markup with SVGO — no signup, nothing leaves your browser.

This free online SVG minifier strips comments, metadata, and excess path precision from your SVG markup using SVGO's optimizer. Paste markup or upload a .svg file, tune a couple of options, and copy the minified result.

Upload SVG file

Remove comments

Remove metadata & titles

Strips <title>, <desc>, and <metadata> elements. Turn off if you rely on <title> for accessibility.

Path precision

Lower values round coordinates more aggressively for smaller files.

Why minify SVGs

SVG files exported from design tools like Illustrator, Figma, or Sketch usually carry a lot of dead weight: XML comments, editor-specific metadata, unused id attributes, and path coordinates with far more decimal precision than any screen can render. None of that affects how the SVG looks — it just adds bytes. Minifying an SVG removes this cruft, which means smaller page weight, faster downloads, and less data parsed by the browser before the icon or illustration paints.

This is especially worth doing for SVGs used repeatedly across a site — icon sprites, logos, inline illustrations — since the savings compound across every page that loads them.

What SVGO's preset-default optimizes

This tool runs SVGO, the standard SVG optimizer most build tools and design software use under the hood. Its default preset removes comments and XML declarations, collapses redundant whitespace, merges paths where safe, drops empty or unused groups and attributes, and rounds numeric precision in path data and coordinates — all while preserving the rendered output.

Frequently asked questions

Paste your SVG markup into the input, or upload a .svg file. The minified output appears automatically on the right, along with a byte-size comparison showing how much smaller it is.

No. Minifying only removes redundant data — comments, metadata, unnecessary whitespace, and excess decimal precision in path coordinates. The rendered appearance stays the same, though reducing precision too aggressively on very detailed paths can occasionally introduce tiny visual differences.

SVGO's default preset strips comments, XML declarations, editor metadata (like Illustrator or Figma export cruft), collapses whitespace, merges paths where possible, and rounds numeric precision — all without altering the visible output.

No. Minification runs locally in your browser using SVGO's client-side library — nothing you paste or upload is ever sent to a server.
