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 and other stuff that can be safely removed 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:

• [ > ] cleanup attributes from newlines, trailing and repeating spaces
• [ > ] remove doctype declaration
• [ > ] remove XML processing instructions
• [ > ] remove comments
• [ > ] remove metadata
• [ > ] remove editors namespaces, elements and attributes
• [ > ] remove empty attributes
• [ > ] remove default "px" unit
• [ > ] remove a lot of hidden elements
• [ > ] remove empty Text elements
• [ > ] remove empty Container elements
• [ > ] convert styles into attributes
• [ > ] convert colors
• [ > ] move elements attributes to the existing group wrapper
• [ > ] collapse groups

But it's not only about rude removing, SVG has a strict specification with a lot of opportunities for optimizations, default values, geometry hacking and more.

How-to instructions and plugins API docs will coming ASAP.

How to use

npm install -g svgo

Usage:
  svgo [OPTIONS] [ARGS]


Options:
  -h, --help : Help
  -v, --version : Version
  -c CONFIG, --config=CONFIG : Local config
  -i INPUT, --input=INPUT : Input file (default: stdin)
  -o OUTPUT, --output=OUTPUT : Output file (default: stdout)

svgo -i myTestFile.svg -o myTestFile.min.svg

TODO

It's only the very first public alpha :)

1. documentation!
2. phantomjs-based server-side SVG rendering "before vs after" tests
3. more unit tests
4. more plugins
