SVGO NPM version Build Status Coverage Status

SVG Optimizer is a Nodejs-based tool for optimizing SVG vector graphics files. npm.io

Why?

SVG files, especially those exported from various editors, usually contain a lot of redundant and useless information. This can include editor metadata, comments, hidden elements, default or non-optimal values and other stuff that can be safely removed or converted without affecting the SVG rendering result.

What it can do

SVGO has a plugin-based architecture, so almost every optimization is a separate plugin.

Today we have:

PluginDescriptionDefault
cleanupAttrscleanup attributes from newlines, trailing, and repeating spacesenabled
inlineStylesmove and merge styles from <style> elements to element style attributesenabled
removeDoctyperemove doctype declarationenabled
removeXMLProcInstremove XML processing instructionsenabled
removeCommentsremove commentsenabled
removeMetadataremove <metadata>enabled
removeTitleremove <title>enabled
removeDescremove <desc>enabled
removeUselessDefsremove elements of <defs> without idenabled

  • with files:

    $ svgo test.svg

    or:

    $ svgo *.svg
    $ svgo test.svg -o test.min.svg
    $ svgo test.svg other.svg third.svg
    $ svgo test.svg other.svg third.svg -o test.min.svg -o other.min.svg -o third.min.svg
  • with STDIN / STDOUT:

    $ cat test.svg | svgo -i - -o - > test.min.svg
  • with folder

    $ svgo -f ../path/to/folder/with/svg/files

    or:

    $ svgo -f ../path/to/folder/with/svg/files -o ../path/to/folder/with/svg/output
    $ svgo *.svg -o ../path/to/folder/with/svg/output
  • with strings:

    $ svgo -s '<svg version="1.1">test</svg>' -o test.min.svg

    or even with Data URI base64:

    $ svgo -s 'data:image/svg+xml;base64,...' -o test.min.svg
  • with SVGZ:

    from .svgz to .svg:

    $ gunzip -c test.svgz | svgo -i - -o test.min.svg

    from .svg to .svgz:

    $ svgo test.svg -o - | gzip -cfq9 > test.svgz
