Minify HTML for production. Fast, secure, and completely free. All processing happens in your browser — no data is sent to any server.
An HTML Minifier removes the whitespace, comments, and formatting that make markup readable to a developer but add nothing to how a browser renders it. It collapses indentation between tags, strips HTML comments, and can compress attribute quoting, producing a smaller file that a browser interprets identically to the original. This is a standard step in production build pipelines, but it's also useful on its own when you need a compact HTML fragment — for an email template, an embedded widget, or a size-constrained response body.
Every byte of HTML has to be downloaded before the browser can start building the page, and while HTML minification typically saves less than CSS or JS minification, it still adds up on documents with heavy indentation and comments — and it's essential when you're embedding HTML somewhere genuinely size-constrained, like an email client with strict size limits, or a webhook payload that needs to stay under a size cap.
No — only whitespace between tags and comments are removed; every element, attribute, and piece of visible content is preserved exactly.
It preserves their content without breaking it, but for maximum size reduction, minify substantial inline CSS/JS separately with the dedicated CSS or JS minifier first.
Slightly, since indentation is gone, but browser DevTools still render the DOM tree normally regardless of source formatting, so element inspection isn't affected.
Yes, void elements like <br>, <img>, and <input> are preserved exactly as written.
No, all processing happens locally in your browser using JavaScript.
