How do I format messy HTML code online?

Paste your unformatted or minified HTML into the input field. The formatter instantly applies proper indentation and line breaks, making the structure readable. Copy the result with one click.

What does HTML formatting actually do?

The formatter adds consistent 2-space indentation for nested elements, line breaks between tags, and normalizes whitespace. It does not change any HTML attributes, values, or the DOM structure — only improves readability.

Can I format HTML copied from a website's source?

Yes — right-click any webpage, select 'View page source', copy the HTML, paste it into the formatter. Useful for inspecting or editing web page templates and email HTML.

Does the formatter validate HTML errors?

The current version focuses on formatting only, not validation. For HTML validation, use the W3C Markup Validation Service. Formatting and validation are separate concerns.

Is the HTML formatter free and private?

Yes — completely free, no account needed. All formatting runs locally in your browser using a custom parser. No HTML is sent to any server.
