HTML Formatter

Format HTML Online — Free HTML Formatter

Paste in messy, minified, or copied-from-a-page HTML and get back clean, properly indented markup you can actually read. Choose your indentation, click Format, and copy the result — no sign-up and nothing to install.

How to Format HTML

Paste your code into the HTML input box, pick an indent size — 2 spaces, 4 spaces, or a tab — and click Format. The tidy version appears in the Result box below, and one click on Copy result puts it on your clipboard. If you want the opposite, click Minify to strip out comments and the whitespace between tags for a smaller file.

What the Formatter Does

Every tag and block of text goes on its own line, and each level of nesting is indented one step further, so it's easy to see which elements sit inside which. Comments are kept in place, and void elements such as br, img, input, meta, and link are recognised as having no closing tag, so they don't push the lines after them out of alignment.

The formatter re-indents the code you give it — it isn't a validator, so it won't fix unclosed tags or other mistakes. And because formatting changes whitespace, it isn't the right choice for content where spacing matters, such as the inside of a pre or textarea block.

Good Uses for This Tool

Reading the minified HTML from a page source or an email template, tidying markup pasted out of a CMS or visual editor, cleaning up a snippet before you commit it or paste it into a bug report, and shrinking a finished template before you send it.

Is It Actually Private?

Yes. The formatting happens entirely in your browser — your code is never uploaded to a server and is not stored anywhere.
