Minify HTML code — remove comments, whitespace, and reduce file size instantly.
HTML Minifier is a free online tool that compresses HTML code by removing unnecessary whitespace, comments, and redundant attributes. The result is a smaller file that loads faster in browsers, improving your website's performance and Core Web Vitals scores. The minification process strips out all formatting whitespace — line breaks, tabs, and extra spaces between tags — while preserving the functional structure of your HTML. It also removes HTML comments, collapses boolean attributes, and optionally removes optional closing tags where safe to do so. This tool is particularly useful for production deployments where every kilobyte matters. Minified HTML reduces bandwidth usage, speeds up page rendering, and improves Time to First Byte (TTFB). It's commonly used alongside CSS and JavaScript minification as part of a complete optimization workflow. Everything runs entirely in your browser. Your HTML code is never uploaded to any server, making it safe for proprietary projects, client work, and sensitive content. There are no usage limits, no file size restrictions, and no account required. Common use cases include preparing HTML for production deployment, optimizing email templates for faster delivery, reducing the size of static HTML pages, and compressing HTML output from template engines. The tool shows before-and-after statistics including file size reduction percentage, character count, and processing time. You can copy the minified result to your clipboard or download it as a file. For the reverse operation — making minified HTML readable again — use the HTML Beautifier tool.
