About this tool

HTML copied from a browser, a CMS or a minified build often arrives as one unreadable line. This formatter re-indents it so each nested element sits one level deeper than its parent, making structure, missing closing tags and misplaced elements easy to spot. It understands void elements such as <br>, <img> and <input> that never have closing tags, and it leaves the contents of <pre>, <textarea>, <script> and <style> exactly as they are, because whitespace inside them is meaningful. Choose two spaces, four spaces or tabs, then copy or download the result. Minify does the reverse, removing comments and collapsing whitespace between tags to reduce page weight for production.

Frequently Asked Questions

Will formatting change how my page looks?
In most cases no. Whitespace between block elements is ignored by browsers. Between inline elements, such as two links or spans side by side, adding or removing a line break can change spacing by one space, so check inline-heavy markup after formatting.
Why is the content of <pre> and <script> not re-indented?
Whitespace inside <pre> and <textarea> is displayed exactly as written, and changing indentation inside <script> or <style> could alter code or strings. Those blocks are preserved verbatim.
Does the formatter fix invalid HTML?
It does not repair or validate markup. It indents what it receives, which often makes problems such as unclosed tags visible. Use the W3C validator to check conformance.
What does Minify remove?
It removes HTML comments and unnecessary whitespace between tags. Content that depends on whitespace, such as text inside <pre>, is kept. For production sites, server compression with gzip or Brotli saves more than minifying alone.
Can I format Vue, Angular or template syntax?
Template expressions like {{ name }} are kept as text, and component tags are indented like regular elements. Complex directives with angle brackets inside attribute values may confuse a plain HTML formatter, so review the output.
