Frequently asked questions

Which formatter does this use?

Prettier's HTML formatter, the same one most front-end projects use, running entirely in your browser.

Is the HTML Beautifier free?

Yes. It is free with no sign-up, and it runs entirely in your browser, so your input is never uploaded or stored.

Will formatting change how my code behaves?

Formatting only changes whitespace and layout. Minifying removes comments and whitespace and may shorten names, so keep the original source in version control.
