+
+[![NPM version](https://img.shields.io/npm/v/html-minifier.svg)](https://www.npmjs.com/package/html-minifier)

+
+[HTMLMinifier](https://kangax.github.io/html-minifier/) is a highly **configurable**, **well-tested**, JavaScript-based HTML minifier.
+
+See [corresponding blog post](http://perfectionkills.com/experimenting-with-html-minifier/) for all the gory details of [how it works](http://perfectionkills.com/experimenting-with-html-minifier/#how_it_works), [description of each option](http://perfectionkills.com/experimenting-with-html-minifier/#options), [testing results](http://perfectionkills.com/experimenting-with-html-minifier/#field_testing) and [conclusions](http://perfectionkills.com/experimenting-with-html-minifier/#cost_and_benefits).
+
+[Test suite is available online](https://kangax.github.io/html-minifier/tests/).

+
+### Sorting attributes / style classes
+
+Minifier options like `sortAttributes` and `sortClassName` won't impact the plain-text size of the output. However, they form long repetitive chains of characters that should improve compression ratio of gzip used in HTTP compression.
+
+## Special cases
+
+### Ignoring chunks of markup
+
+If you have chunks of markup you would like preserved, you can wrap them `<!-- htmlmin:ignore -->`.
+
+### Preserving SVG tags
+
+SVG tags are automatically recognized, and when they are minified, both case-sensitivity and closing-slashes are preserved, regardless of the minification settings used for the rest of the file.
+
+### Working with invalid markup
+
+HTMLMinifier **can't work with invalid or partial chunks of markup**. This is because it parses markup into a tree structure, then modifies it (removing anything that was specified for removal, ignoring anything that was specified to be ignored, etc.), then it creates a markup out of that tree and returns it.
+
+Input markup (e.g. `<p id="">foo`)
+
+↓
+
+Internal representation of markup in a form of tree (e.g. `{ tag: "p", attr: "id", children: ["foo"] }`)
+
+↓
+
+Transformation of internal representation (e.g. removal of `id` attribute)
+
+↓
+
+Output of resulting markup (e.g. `<p>foo</p>`)
+
+HTMLMinifier can't know that original markup was only half of the tree; it does its best to try to parse it as a full tree and it loses information about tree being malformed or partial in the beginning. As a result, it can't create a partial/malformed tree at the time of the output.
+
+## Installation Instructions
+
+From NPM for use as a command line app:
+
+```shell
+npm install html-minifier -g
+```
+
+From NPM for programmatic use:
+
+```shell
+npm install html-minifier
+```
+
+From Git:
+
+```shell
+git clone git://github.com/kangax/html-minifier.git
+cd html-minifier
+npm link .
+```
+
+## Usage
+
+Note that almost all options are disabled by default. For command line usage please see `html-minifier --help` for a list of available options. Experiment and find what works best for you and your project.
+
+* **Sample command line:** ``html-minifier --collapse-whitespace --remove-comments --remove-optional-tags --remove-redundant-attributes --remove-script-type-attributes --remove-tag-whitespace --use-short-doctype --minify-css true --minify-js true``
+
+### Node.js
+
+```js
+var minify = require('html-minifier').minify;
+var result = minify('<p title="blah" id="moo">foo</p>', {
+  removeAttributeQuotes: true
+});
+result; // '<p title=blah id=moo>foo</p>'
+```
+
+## Running benchmarks
+
+Benchmarks for minified HTML:
+
+```shell
+node benchmark.js
+```
