About the HTML Formatter

Clean up HTML copied from a CMS, email builder or minified page. Tags are indented by nesting level, and inline <style> and <script> blocks are formatted too. Powered by the widely used js-beautify library.

Your data is processed in the browser and never sent to a server, so it is safe to paste payloads that contain tokens or personal data.

How to use it

  1. Paste HTML or open a file.
  2. Choose indentation and optional line wrapping.
  3. Copy or download the formatted HTML.

Good to know

  • Formatting changes whitespace only. In rare cases whitespace between inline elements affects rendering; check the result visually.
  • Invalid HTML is formatted as best as possible but not corrected.

Frequently asked questions

Does it minify HTML too?

No. Use a build tool for HTML minification; this tool focuses on readability.

Is the HTML rendered or executed?

No, it is processed as text only.
