How to use SVG Optimizer

Get the best out of SVG Optimizer: every option explained, a worked example, and what to check when the output is not what you expected.

Updated July 31, 2026

What it does

Compress, clean, and strip useless metadata and editor groups from SVG vectors entirely offline. It runs entirely in your browser — your input never leaves your device.

Options

Every setting this tool exposes, straight from the code that validates it.

OptionTypeDefaultWhat it does
svgtextSVG markup to optimize. Required.
removeXmlDecltrue / falsetrueDefaults to true.
removeMetatrue / falsetrueDefaults to true.
removeCommentstrue / falsetrueDefaults to true.
minifytrue / falsefalseStrips all optional whitespace to produce the smallest possible output, on one line. Defaults to false.

Worked example

Run these settings on the tool page:

  • svg: <svg viewBox="0 0 10 10"><circle cx="5" cy="5" r="4"/></svg>
  • removeXmlDecl: true
  • removeMeta: true
  • removeComments: true
  • minify: false

You get:

<<svg viewBox="0 0 10 10">
  <circle cx="5" cy="5" r="4"/>
</svg>>

Getting the result you want

Most of the control here is in the options above. If the output is not what you expected, the setting to check first is removeXmlDecl and removeMeta — those change the shape of the output rather than the input it accepts.

Troubleshooting

  • Nothing happens / the output stays empty. svg is required — the tool waits until you provide it.
  • It is slow on very large input. Everything runs in your browser, so speed depends on your device. Very large inputs are best split up, or run through the API where the work happens on our servers.

Automating it

The same logic is available as a REST endpoint, so you can run it from a script, a CI job or your own app.

Bash
curl "https://api.toolsxpo.com/v1/svg-optimizer" \
  -H "Authorization: Bearer $TOOLSXPO_KEY"

It costs 1 credit per successful call. See the full endpoint reference, or try it in the playground.
