What is HTML Formatter & Beautifier?

The HTML Formatter re-indents HTML so the nesting of elements is easy to read. Paste minified or messy markup — from a CMS, email builder or browser DevTools — and get consistently indented code with each block element on its own line. Choose 2 spaces, 4 spaces or tabs. Formatting only changes whitespace between tags, so the rendered page looks the same.

Frequently asked questions

Will formatting change how my page looks?

Normally no. Only whitespace between tags changes; content inside <pre> and <textarea> is left alone.

Does it fix invalid HTML?

It re-indents what you give it but does not repair missing closing tags. Unbalanced tags will show up as odd indentation.

Can it format inline CSS and JavaScript?

Yes. Embedded <style> and <script> blocks are indented as well.
