Is this as good as SVGO?

No. SVGO is a full AST-based optimiser that rewrites paths, deduplicates gradients and collapses groups. This tool is a fast, dependency-free regex-based cleaner for the most common bloat. For icon-set work, run SVGO separately.

Will optimisation break my SVG?

The optimisations are conservative — they only remove comments, declarations, editor namespaces, metadata, default attributes and whitespace. They never touch geometry, paths or styling. The rendered preview lets you visually verify nothing was lost.

Why are Inkscape and Sodipodi namespaces removed?

They are editor-specific metadata that adds nothing to rendering. Removing them shrinks the file and avoids leaking authoring-tool fingerprints.

Can I keep the XML declaration?

Yes — toggle off “Remove XML declaration”. The declaration is only required when the SVG is served as a standalone .svg file with a non-UTF-8 encoding; for inline HTML use it is unnecessary.

Design Tools

SVG Optimizer

Paste SVG markup and remove the bloat that illustration tools leave behind — comments, XML declarations, editor namespaces (Inkscape, Sodipodi, XLink), <metadata> blocks, default attributes and redundant whitespace. See before/after size and copy the clean SVG.

Your input is processed locally in your browser. It is not uploaded to Dueneo.

How to use

1
Paste your SVG
Drop raw SVG markup into the left-hand editor. The textarea handles multi-line input and preserves whitespace — exactly what export tools produce.
2
Choose optimisations
Toggle which cleanups to apply: comments, XML declaration, editor namespaces (Inkscape/Sodipodi/XLink), <metadata> blocks, default attributes and whitespace.
3
Optimise
Click Optimise SVG. The cleaned-up markup appears on the right, with before/after size and a rendered preview.
4
Copy or download
Use Copy to put the SVG on your clipboard, or Save to download it as optimised.svg.

Common use cases

Shrink icon SVGs exported from Illustrator or Inkscape before committing them.
Strip editor cruft (sodipodi:namedview, inkscape:label) from a designer's hand-off.
Minify SVG sprites to reduce the size of an inline icon system.
Preview an optimised SVG to make sure no geometry was accidentally removed.

Limitations

This is a regex-based optimiser. It does not parse the SVG tree, so it cannot deduplicate gradients, collapse groups or rewrite paths the way SVGO can.
Inputs larger than 1 MB are rejected to keep the tab responsive.
Inline <script> tags are not stripped — do not paste untrusted SVG into shared documents.
The rendered preview uses dangerouslySetInnerHTML; modern browsers do not execute inline scripts injected this way, but CSP rules on your site may differ.
