HTML Formatter
Format and beautify HTML markup, including Tailwind class lists.
About this tool
Format and beautify HTML: nested tags are indented one level at a time, short elements stay on one line, and <pre>, <script>, and <style> blocks are left untouched.
How to use
Paste compacted markup, run Format, verify tags still balance, then continue in your editor.
Example
Compact hero markup expands into a readable tree.
Input
<section class="hero"><h1>CSS to Tailwind</h1><p>Convert utilities in the browser.</p><a href="/">Open</a></section>Output
<section class="hero">
<h1>CSS to Tailwind</h1>
<p>Convert utilities in the browser.</p>
<a href="/">Open</a>
</section>Tip
Formatting will not fix invalid HTML — validators still matter.
Good to know
Is an HTML beautifier different from an HTML formatter?
No. Both re-indent nested markup, so this page covers both searches with one tool.
What does it leave alone, and will it fix invalid HTML?
Content inside <pre>, <textarea>, <script>, and <style> is kept exactly as written. The tool only re-indents: unclosed or misnested tags stay as they are, so run a validator when structure matters.
