Questions

How do I minify HTML code?
Paste your HTML into the input field and the tool will remove comments, collapse whitespace, and strip optional closing tags and redundant attributes to produce the smallest valid HTML output.
Does HTML minification affect how the page looks?
No, properly minified HTML renders identically in browsers. The minifier only removes characters that have no effect on rendering, such as extra whitespace between tags and HTML comments.
Does the HTML minifier also minify inline CSS and JavaScript?
The minifier focuses on HTML structure. Inline CSS and JavaScript within the document are left as-is. For those, use the dedicated CSS Minifier or JavaScript Minifier tools.
Is the HTML minifier safe for production use?
The output is valid HTML that renders correctly in all modern browsers. Always test on your target browsers before deploying, especially if you rely on whitespace-sensitive elements like pre tags.
