HTML Formatter

Format and beautify messy HTML code with proper indentation, or minify it to reduce file size. Supports customizable indent size and handles self-closing tags correctly.

How to use

  1. Paste your HTML snippet or full page markup into the editor.
  2. Click Beautify to re-indent and clean up messy HTML for readability.
  3. Adjust indentation to match your project’s HTML style guide.
  4. Use Minify when you need smaller output for inline embeds or production templates.
  5. Copy the formatted HTML back into your project and validate it in the browser.

FAQ

Can this format HTML generated by frameworks (JSX/Vue templates)?

It works best on plain HTML. If you paste template syntax, results may vary depending on the markup.

Does it reformat code inside <script> or <style> tags?

It preserves the contents, but it’s not a dedicated JavaScript/CSS formatter. For those blocks, use the specific tools.

Is my HTML uploaded to a server for formatting?

No. Formatting runs locally in your browser, so your markup stays private.

How do I beautify HTML from a minified single-line file?

Paste the minified HTML and click Beautify to reintroduce line breaks and indentation for easier editing.
