Frequently Asked Questions
What does the HTML Formatter do?
It parses messy or minified HTML and re-indents it consistently, collapsing inline content like text and <span>/<a> tags onto flowing lines while breaking block elements onto their own lines.
Does it preserve <script>, <style>, and <pre> content?
Yes. Content inside <script>, <style>, <pre>, and <textarea> is preserved verbatim rather than re-indented or collapsed, since whitespace matters there.
Can I choose the indent size?
Yes. Choose 2-space or 4-space indentation to match your project's style.
Does it fix malformed HTML?
It tolerates minor issues like stray or mismatched end tags by ignoring what it can't match, so you get formatted output even from imperfect markup. It is not a full HTML validator.
Is this free to use?
Yes. The HTML Formatter is completely free with no signup, no login, and no limits.
