SVGO

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

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:, Plugin, Description, Default, ------, -----------, -------, cleanupAttrs, cleanup attributes from newlines, trailing, and repeating spaces, enabled, inlineStyles, move and merge styles from <style> elements to element style attributes, enabled, removeDoctype, remove doctype declaration, enabled, removeXMLProcInst, remove XML processing instructions, enabled, removeComments, remove comments, enabled, removeMetadata, remove <metadata>, enabled, removeTitle, remove <title>, enabled, removeDesc, remove <desc>, enabled, removeUselessDefs, remove elements of <defs> without id, enabled, removeXMLNS, removes xmlns attribute (for inline svg), disabled, removeEditorsNSData, remove editors namespaces, elements, and attributes, enabled, removeEmptyAttrs, remove empty attributes, enabled, removeHiddenElems, remove hidden elements, enabled, removeEmptyText, remove empty Text elements, enabled, removeEmptyContainers, remove empty Container elements, enabled, removeViewBox, remove viewBox attribute when possible, enabled, cleanupEnableBackground, remove or cleanup enable-background attribute when possible, enabled, minifyStyles, minify <style> elements content with CSSO, enabled, convertStyleToAttrs, convert styles into attributes, enabled, convertColors, convert colors (from rgb() to #rrggbb, from #rrggbb to #rgb), enabled, convertPathData, convert Path data to relative or absolute (whichever is shorter), convert one segment to another, trim useless delimiters, smart rounding, and much more, enabled, convertTransform, collapse multiple transforms into one, convert matrices to the short aliases, and much more, enabled, removeUnknownsAndDefaults, remove unknown elements content and attributes, remove attrs with default values, enabled, removeNonInheritableGroupAttrs, remove non-inheritable group's "presentation" attributes, enabled, removeUselessStrokeAndFill, remove useless stroke and fill attrs, enabled, removeUnusedNS, remove unused namespaces declaration, enabled, prefixIds, prefix IDs and classes with the SVG filename or an arbitrary string, disabled, cleanupIDs, remove unused and minify used IDs, enabled, cleanupNumericValues, round numeric values to the fixed precision, remove default px units, enabled, cleanupListOfValues, round numeric values in attributes that take a list of numbers (like viewBox or enable-background), disabled, moveElemsAttrsToGroup, move elements' attributes to their enclosing group, enabled, moveGroupAttrsToElems, move some group attributes to the contained elements, enabled, collapseGroups, collapse useless groups, enabled, removeRasterImages, remove raster images, disabled, mergePaths, merge multiple Paths into one, enabled, convertShapeToPath, convert some basic shapes to <path>, enabled, convertEllipseToCircle, convert non-eccentric <ellipse> to <circle>, enabled, sortAttrs, sort element attributes for epic readability, disabled, sortDefsChildren, sort children of <defs> in order to improve compression, enabled, removeDimensions, remove width/height and add viewBox if it's missing (opposite to removeViewBox, disable it first), disabled, removeAttrs, remove attributes by pattern, disabled, removeAttributesBySelector, removes attributes of elements that match a css selector, disabled, removeElementsByAttr, remove arbitrary elements by ID or className, disabled, addClassesToSVGElement, add classnames to an outer <svg> element, disabled, addAttributesToSVGElement, adds attributes to an outer <svg> element, disabled, removeOffCanvasPaths, removes elements that are drawn outside of the viewbox, disabled, removeStyleElement, remove <style> elements, disabled, removeScriptElement, remove <script> elements, disabled, reusePaths, Find duplicated elements and replace them with links, disabled, Want to know how it works and how to write your own plugin?

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 or JSON string to extend or replace default
  --disable=PLUGIN : Disable plugin by name, "--disable=PLUGIN1,PLUGIN2" for multiple plugins
  --enable=PLUGIN : Enable plugin by name, "--enable=PLUGIN3,PLUGIN4" for multiple plugins
  --datauri=DATAURI : Output as Data URI string (base64, URI encoded or unencoded)
  --multipass : Pass over SVGs multiple times to ensure all optimizations are applied
  --pretty : Make SVG pretty printed
  --indent=INDENT : Indent number when pretty printing SVGs
  -r, --recursive : Use with '-f'. Optimizes *.svg files in folders recursively.
  -q, --quiet : Only output error messages, not regular status messages
  --show-plugins : Show available plugins and exit

Arguments:
  INPUT : Alias to --input

• 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:
