HTML Beautifier

Why beautify HTML?

  • Readability — Properly indented HTML is dramatically easier to scan, debug, and maintain. Nested structure becomes instantly visible.
  • Code review — Reviewers can read formatted HTML without fighting with minified one-liners.
  • Debugging — Browser dev tools re-indent HTML too, but having it formatted in source helps you spot unclosed tags and structure errors before they reach the browser.
  • CMS output — Many CMSs output sloppy HTML. Paste it here before working with it.

Frequently Asked Questions

No — browsers collapse whitespace between tags, so adding or removing indentation has no visual effect. The exception is whitespace inside <pre> and <textarea> elements, which this tool leaves untouched to preserve their content exactly.
This is intentional. The content inside <script> and <style> tags is JavaScript and CSS, not HTML — re-indenting it with the HTML indenter would mangle the code. For formatting inline scripts and styles, use the JS Beautifier and CSS Beautifier separately.
