Every byte of HTML your server sends is a byte the browser has to download before a page can render, so trimming the excess directly improves load time and Core Web Vitals. Our free HTML Minifier is a dependable html minifier online that strips the formatting whitespace, indentation, and comments browsers don't need while leaving your markup's structure and behavior completely intact.
Paste a template or full document to compress html code in a single click and see the exact before-and-after byte count alongside the percentage saved, a clear way to reduce html size across landing pages, email templates, and server responses. Unlike naive tools that mangle everything, this html optimizer is whitespace-safe: the contents of pre, textarea, script, and style tags, plus IE conditional comments, are preserved verbatim so significant spacing and embedded JavaScript or CSS strings survive untouched. A built-in sample lets you try it instantly, you can minify html free with no limits, and the result copies or downloads as a ready-to-ship .html file.
All processing runs inside your browser, so proprietary markup and unreleased pages never leave your device. Chain it with our CSS Minifier and JavaScript Minifier to shrink your entire front-end bundle, tidy data files with the JSON Formatter, or fine-tune search-and-replace tasks using the Regex Tester.
