Key Features

  • 100% private — runs entirely in your browser; nothing is sent or stored.

FAQs

Will it break my HTML?

It only removes comments and collapses whitespace; tags and attributes are untouched. Always test the result in a browser before deploying.

Does it affect preformatted text?

Whitespace is collapsed everywhere, including inside pre tags, so check preformatted blocks afterwards if spacing matters there.

Can it handle large files?

Yes. Everything is processed locally in your browser, so even large pages minify in a fraction of a second.
