What is HTML Minification?

HTML minification reduces file size by removing unnecessary characters like comments, extra whitespace, and optional closing tags. Smaller HTML files load faster and use less bandwidth, which improves both user experience and search engine rankings. This tool runs entirely in your browser. No data is sent to any server.

Features

Remove HTML comments, collapse whitespace, strip optional closing tags (like </p>, </li>, </td>), remove unnecessary attribute quotes, remove empty attributes, and minify inline CSS and JavaScript. Content inside <pre>, <code>, and <textarea> tags is preserved as-is to maintain formatting.
