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:

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

Installation

$ [sudo] npm install -g svgo

Usage

CLI

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 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:

  $ 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
