SVG Cleaner

Minify and clean SVG markup for smaller file sizes. All processing occurs locally in your browser.

SVG Cleaner: related tools

Strips SVG markup down to a single compact line. It removes comments, collapses every run of whitespace to one space, deletes the gap between a closing and an opening tag, and removes spaces around braces, semicolons and colons. The result is shown back as plain text you can copy.

SVG Cleaner: how to use it

Paste the SVG source into the box, replacing the small circle example if you like.
Press Clean SVG; the compacted markup appears directly underneath.
Select the result and copy it into your file or data URI.

SVG Cleaner: worked example

<svg width="100" height="100">
  <circle cx="50" cy="50" r="40" fill="blue" />
</svg>

becomes<svg width="100" height="100"><circle cx="50" cy="50" r="40" fill="blue" /></svg>

The space before the self-closing slash is inside the tag and survives; the newline and indentation between the tags do not.

<svg>
  <!-- note -->
  <text>Hello   World</text>
</svg>

becomes<svg><text>Hello World</text></svg>

The comment is gone, and the run of three spaces inside the text node has collapsed to one.

SVG Cleaner: when to use it

Shrinking a hand-written icon before inlining it in HTML.
Removing editor comments and indentation from an exported file.
Getting a one-line SVG to drop into a data URI or a JSX attribute.

SVG Cleaner: what it does not do

The whitespace rule applies inside text nodes as well, so <text>Hello World</text> becomes <text>Hello World</text> and the rendered spacing changes.
The punctuation rule reaches outside tags too: a caption reading Note: hi comes back as Note:hi, and CSS inside a style block loses the spaces around its braces and colons.
It is not an optimiser: no attribute removal, no metadata, title or desc stripping, no path rewriting, and no check that the input is well-formed SVG.
It is a plain text transform and cannot distinguish markup from character data, so it will happily edit the visible words in a drawing as well as the structure.
