HTML Minifier
Strip comments, whitespace and unnecessary line breaks from your HTML to reduce file size — all in your browser, nothing uploaded.
Why minify HTML?
Every comment, extra space, and line break in your HTML file adds bytes that browsers have to download before rendering your page. On a small page this barely matters — but across a whole site, it adds up.
Minifying strips out everything that's only there for human readability, without changing how the page actually renders. It's a simple, safe way to shave a bit of load time off your site.
Frequently asked questions
Will minifying break my HTML?
This tool only removes comments, whitespace and line breaks — it doesn't change tags, attributes or content, so your page should render identically.
Should I keep an unminified copy?
Yes — keep your original, readable HTML as your working copy, and only use the minified version for what you actually deploy to your live site.
Is my code uploaded anywhere?
No — minification happens entirely in your browser. Nothing you paste here is sent to our servers.
