SVG Optimizer

Paste SVG markup and get a cleaned, minified version — removes comments, metadata, and redundant attributes. Runs entirely in your browser.

Output:

What does the SVG Optimizer remove?

  • XML declarations — <?xml version="1.0"?> is not needed in HTML5 documents.
  • Comments — <!-- … --> blocks serve no visual purpose once deployed.
  • Metadata elements — <metadata> blocks generated by design tools are ignored by browsers.
  • data-* attributes — Tool-specific data attributes not used by the browser renderer.
  • Default attribute values — Attributes like stroke="none" and opacity="1" match SVG defaults and have no visual effect.
  • Empty groups — <g></g> elements with no children and no attributes are inert.
  • Unused namespace declarations — xmlns:xlink when no xlink attributes are present in the SVG.

Minified vs Formatted

Minified collapses all whitespace between tags, producing the smallest possible output. Use this for production — CSS background-image, data URIs, or any context where file size matters.

Formatted keeps the SVG human-readable with consistent two-space indentation. Use this when you need to inspect or further edit the optimized output.

Frequently Asked Questions

Will optimization change how my SVG looks?+

No. The optimizer only removes elements and attributes that have no effect on rendering — comments, metadata, and attributes whose values match the SVG specification defaults. The preview shows the optimized SVG so you can verify visually before copying.

Is this the same as SVGO?+

No. SVGO is a full Node.js library with dozens of plugins including path data merging, coordinate precision reduction, and more. This tool applies a focused subset of safe, lossless optimizations that run entirely in your browser — no install, no upload, no dependencies.

Is my SVG sent to a server?+

No. All optimization happens in your browser using the built-in DOM parser and serializer. Your SVG markup never leaves your device.

What does this optimizer not do?+

This optimizer does not rewrite path data, merge paths, reduce decimal precision, collapse transformations, or remove IDs and classes that might be referenced by CSS or JavaScript. It applies only safe, lossless structural cleanup. For deeper compression, use SVGO with specific plugins configured for your SVG.
