Optimise inline SVG with PostCSS.
With npm do:
npm install postcss-svgo --save
h1 {
background: url('data:image/svg+xml;charset=utf-8,<?xml version="1.0" encoding="utf-8"?><!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd"><svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" xml:space="preserve"><circle cx="50" cy="50" r="40" fill="yellow" /></svg>');

svgo([options])Type: boolean
Default: undefined
If true, it will encode URL-unsafe characters such as <, > and &;
false will decode these characters, and undefined will neither encode nor
decode the original input. Note that regardless of this setting, # will
always be URL-encoded.
Optionally, you can customise the output by specifying the plugins option. You
will need to provide the config in comma separated objects, like the example
below. Note that you can either disable the plugin by setting it to false,
or pass different options to change the default behaviour.
var postcss = require('postcss');
var svgo = require('postcss-svgo');
var opts = {
plugins: [{
removeDoctype: false
}, {
removeComments: false
}, {
cleanupNumericValues: {
floatPrecision: 2
}
}, {
convertColors: {
names2hex: false,
rgb2hex: false
}
}]
};
postcss([ svgo(opts) ]).process(css).then(function (result) {
console.log(result.css)
});

SVGO is the underlying library that postcss-svgo uses for optimizing SVG files. It can be used directly on SVG files, rather than through CSS, providing a more general-purpose tool for SVG optimization.
This is a Gulp plugin that uses SVGO to optimize SVG files. It's similar to postcss-svgo but is designed to be used in a Gulp-based build process, making it more suitable for workflows that are already using Gulp.
imagemin-svgo is a plugin for Imagemin, another build tool, that also uses SVGO for optimizing SVG files. It's comparable to postcss-svgo but is tailored for use with Imagemin, which can handle various image formats, not just SVG.
This is a Grunt plugin that leverages SVGO to optimize SVG files. It's an alternative to postcss-svgo for those who are using Grunt in their build process.
