SVGO

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

Why?

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

What it can do

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

Today we have:

• [ cleanupAttrs ] cleanup attributes from newlines, trailing and repeating spaces
• [ removeDoctype ] remove doctype declaration
• [ removeXMLProcInst ] remove XML processing instructions
• [ removeComments ] remove comments
• [ removeMetadata ] remove <metadata>
• [ removeTitle ] remove <title> (disabled by default)
• [ removeDesc ] remove <desc> (only non-meaningful by default)
• [ removeUselessDefs ] remove elements of <defs> without id
• [ removeEditorsNSData ] remove editors namespaces, elements and attributes
• [ removeEmptyAttrs ] remove empty attributes
• [ removeHiddenElems ] remove hidden elements
• [ removeEmptyText ] remove empty Text elements
• [ removeEmptyContainers ] remove empty Container elements
• [ removeViewBox ] remove viewBox attribute when possible (disabled by default)
• [ cleanUpEnableBackground ] remove or cleanup enable-background attribute when possible
• [ convertTyleToAttrs ] convert styles into attributes
• [ convertColors ] convert colors (from rgb() to #rrggbb, from #rrggbb to #rgb)
• [ convertPathData ] convert Path data to relative or absolute whichever is shorter, convert one segment to another, trim useless delimiters, smart rounding and much more
• [ convertTransform ] collapse multiple transforms into one, convert matrices to the short aliases and much more
• [ removeUnknownsAndDefaults ] remove unknown elements content and attributes, remove attrs with default values
• [ removeNonInheritableGroupAttrs ] remove non-inheritable group's "presentation" attributes
• [ removeUselessStrokeAndFill ] remove useless stroke and fill attrs
• [ removeUnusedNS ] remove unused namespaces declaration
• [ cleanupIDs ] remove unused and minify used IDs
• [ cleanupNumericValues ] round numeric values to the fixed precision, remove default 'px' units
• [ moveElemsAttrsToGroup ] move elements attributes to the existing group wrapper
• [ moveGroupAttrsToElems ] move some group attributes to the content elements
• [ collapseGroups ] collapse useless groups
• [ removeRasterImages ] remove raster images (disabled by default)
• [ mergePaths ] merge multiple Paths into one
• [ convertShapeToPath ] convert some basic shapes to path
• [ sortAttrs ] sort element attributes for epic readability (disabled by default)
• [ transformsWithOnePath ] apply transforms, crop by real width, center vertical alignment and resize SVG with one Path inside (disabled by default)
• [ removeDimensions ] remove width/height attributes if viewBox is present (disabled by default)
• [ removeAttrs ] remove attributes by pattern (disabled by default)
• [ addClassesToSVGElement ] add classnames to an outer <svg> element (disabled by default)

Want to know how it works and how to write your own plugin? Of course you want to.

How to use

$ [sudo] npm install -g svgo

Usage:
  svgo [OPTIONS] [ARGS]

Options:
  -h, --help : Help
  -v, --version : Version
  -i INPUT, --input=INPUT : Input file, "-" for STDIN
  -s STRING, --string=STRING : Input SVG data string
  -f FOLDER, --folder=FOLDER : Input folder, optimize and rewrite all *.svg files
  -o OUTPUT, --output=OUTPUT : Output file or folder (by default the same as the input), "-" for STDOUT
  -p PRECISION, --precision=PRECISION : Set number of digits in the fractional part, overrides plugins params
  --config=CONFIG : Config file to extend or replace default
  --disable=DISABLE : Disable plugin by name
  --enable=ENABLE : Enable plugin by name
  --datauri=DATAURI : Output as Data URI string (base64, URI encoded or unencoded)
  --pretty : Make SVG pretty printed
  --show-plugins : Show available plugins and exit

Arguments:
  INPUT : Alias to --input
  OUTPUT : Alias to --output

• with files:

    $ svgo test.svg
  

  or:

    $ svgo test.svg test.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
  

• 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
