Messy HTML is difficult to read, debug, and maintain. Our free online HTML Formatter beautifies your HTML code with proper indentation, consistent formatting, and clean structure — making it easy to understand at a glance.
The formatter handles standard HTML elements, void tags (like <br>, <img>, <input>), nested structures, and inline content. It adds appropriate indentation levels for nested elements while keeping inline content readable.
Perfect for cleaning up minified HTML, formatting code generated by CMS platforms, or preparing HTML for documentation and code reviews. Everything runs in your browser — no data is sent to any server.
