Will it break inline scripts or styles?

No. Script, style, pre, and textarea blocks are left exactly as written; only the surrounding whitespace is collapsed.

Does it minify inline CSS and JS?

No. It only touches markup whitespace and comments. Minify CSS and JS separately for best results.

What the HTML minifier does

It strips ordinary comments and collapses whitespace between tags to reduce byte size, while leaving script, style, pre, and textarea contents untouched.

Why minify HTML

Smaller markup means faster downloads and quicker first paint. It is a low-effort optimisation for landing pages and emails.

Safe by design

Conditional comments and the contents of code and preformatted blocks are preserved, so minification will not silently break scripts or layout.
