HTML Formatter

Beautify and minify HTML code. Clean up messy markup or strip it down for production.

About This Tool

Free HTML formatter and beautifier online — paste messy, minified, or unindented HTML and get it back clean and properly indented in one click. No sign-up, no upload, instant browser-based processing. HTML that has been minified for production (to reduce page load times) is almost impossible to read. This tool reverses that: it parses the HTML structure and re-indents each element correctly so you can read, edit, and understand the markup. Web developers use this to inspect third-party HTML widgets, debug template output from CMS platforms, format email HTML templates, and review pulled web page source code. The formatter handles nested elements, attributes, inline styles, and embedded scripts and styles correctly.

Frequently Asked Questions

Yes. You can choose 2-space, 4-space, or tab indentation depending on your project coding style.
