Frequently asked questions

Does this work on already-minified code?

Yes — that's the main use case. Paste minified HTML, CSS, or JS and get readable, indented output.

Will this change my code's behavior?

No. Beautifying only changes whitespace and indentation, not logic or structure.

Is my code uploaded anywhere?

No. Formatting happens entirely in your browser.
