About HTML Formatter

The HTML Formatter beautifies messy or minified HTML into clean, properly indented markup with consistent nesting, so it's easy to read and edit. It's the fast fix for source copied from a page or generated by a tool that stripped all the whitespace. Formatting runs locally in your browser with nothing uploaded. To render the result, use the HTML Viewer, and format your styles with the CSS Formatter.

Frequently Asked Questions

Does formatting change how the page renders?

No. Formatting only adds indentation and line breaks between tags for readability. The structure and rendered output stay identical to the original markup.

Can it clean up minified HTML?

Yes. Paste single-line or minified HTML and the formatter expands it into a properly nested, indented document that's much easier to work with.

Is HTML Formatter free to use?

Yes. HTML Formatter is completely free with no sign-up, no subscription, and no usage limits. Every tool on CodeUtilityKit is free forever.

Is my data safe when I use HTML Formatter?

Absolutely. HTML Formatter runs entirely in your browser. Your input is processed locally with JavaScript and is never sent to, stored on, or logged by any server — so it is safe even for private or sensitive data.
