Free Online HTML Minifier & Compressor
Paste your HTML above and click Minify. The tool removes unnecessary code according to the options you select and shows the exact size reduction.
Why minify HTML?
HTML minification removes bytes a browser does not need, such as unnecessary whitespace, comments and redundant attributes. Smaller HTML can reduce transfer size and is useful when preparing pages, templates, email markup or production output.
Private, browser-based HTML compression
Your HTML is processed locally by JavaScript in your browser. The code you paste into the editor is not sent to our server for minification.
What can this HTML minifier optimize?
You can collapse whitespace, remove HTML comments, optional tags and redundant attributes, shorten the doctype, and minify inline CSS and JavaScript. Advanced options let you choose how aggressively the markup is compressed.
How to minify HTML online
Paste HTML into the input box, choose the options you need, click Minify, then copy the compressed HTML from the output box. Check the result in your project before deploying aggressive options.
