Free HTML Minifier Online
Paste or upload your HTML and compress it instantly in your browser. Removes comments, whitespace, and redundant markup — inline CSS and JS minified too.
About the HTML Minifier
HTML minification removes everything that browsers don't need to render your page correctly: whitespace between tags, HTML comments, and unnecessary newlines. The resulting file is smaller, which means faster downloads and reduced bandwidth costs.
MinifyTools also minifies inline <style> and <script> blocks within your HTML, applying full CSS and JavaScript minification rules to embedded code. Pre-formatted blocks (<pre>, <textarea>) are preserved as-is.
All processing happens locally in your browser — your HTML is never sent to any server.
HTML Minifier FAQ
What does the HTML minifier remove?
It removes HTML comments, unnecessary whitespace between tags, redundant newlines, and leading/trailing spaces. Inline <style> and <script> blocks are also minified using CSS and JavaScript rules.
Will minifying HTML break my page layout?
No. Whitespace between block-level elements has no visual effect. Inline elements like <span> can occasionally be affected if you rely on whitespace between them, so review the output if your layout uses inline text nodes.
How much can HTML minification save?
Typical savings range from 15–30%. Pages with lots of comments or indented templates see larger reductions. Combined with gzip/Brotli compression on your server, HTML size can be reduced by 80%+ total.
