What does the SVG Optimizer remove?

It removes XML comments, blocks, editor-specific namespace declarations and attributes (inkscape:*, sodipodi:*, dc:*, cc:*, rdf:*), the declaration, the xmlns:xlink namespace if no xlinks are used, and enable-background attributes. It also collapses whitespace between tags.

Will optimizing break my SVG visually?

No. The optimizer only removes non-visual metadata and editor artifacts that have no effect on how the SVG renders. Your shapes, colors, paths, and animations are preserved. Always test in your target environment after optimizing.

What is the 'Strip Unused IDs' option?

SVG editors often add id attributes to every element for their own internal tracking. If an id is not referenced by a url(#id), href, or xlink:href, it serves no purpose in the browser. This option safely removes such unreferenced IDs to further reduce file size.

Why remove the XML declaration?

The declaration is optional for SVG files used inline in HTML or as img src. Browsers handle UTF-8 SVG without it. Removing it saves a few bytes and is safe for most web use cases.

Is my SVG data sent to a server?

No. All optimization happens entirely in your browser using JavaScript string manipulation. Your SVG code never leaves your computer.
