HTML Minifier

Minify HTML online: strip comments and collapse whitespace. See before and after file sizes. Free and private.

Frequently asked questions

How much does it compress?
It reports the exact before and after byte counts. Real savings depend on how much whitespace and comments your HTML has.
Is the output safe for production?
It removes comments and collapses whitespace between tags. Contents of pre, textarea, script and style blocks are preserved so layout and code keep working.
Does it upload my HTML?
No. Minifying happens entirely in your browser.
Does it minify inline JavaScript and CSS?
No, inline scripts and styles are preserved byte-for-byte. Use a dedicated JS or CSS minifier for those.

This tool runs entirely in your browser. No data is uploaded anywhere.
