Frequently Asked Questions
Will minifying break my HTML?
No, as long as the markup is valid. Minification removes only insignificant whitespace and comments; visible content and structure are preserved.
Does whitespace ever matter in HTML?
Inside <pre>, <textarea>, and elements styled with white-space: pre, spacing is significant. Good minifiers leave those untouched.
Is minifying the same as compression?
No — minification reduces the source text; gzip/brotli compression is applied by the server on top. Using both gives the smallest transfer size.
