Messy, minified, or auto-generated HTML is hard to read and maintain. Our free HTML formatter takes any HTML string and outputs it with consistent indentation, making nesting levels visually clear. Useful for cleaning up HTML copied from browser DevTools, prettifying template output, or reviewing generated code. Works entirely in your browser — no data is sent to a server.

Frequently Asked Questions

Does this validate HTML? expand_more
The formatter uses the browser's DOMParser which will fix minor issues, but it does not report W3C validation errors.
Can I format HTML that contains inline CSS or JavaScript? expand_more
Yes. The formatter processes the entire HTML document including embedded style and script blocks.
