Frequently Asked Questions

Which languages are supported?

Local formatting for JavaScript, CSS, HTML, and SQL, with indentation of 2/4 spaces or tabs.

Does formatting change the code logic?

No. Formatting only adjusts indentation, line breaks, and spacing — it never changes semantics.

Can I copy or download the result?

Yes. Copy in one click, or download the file with the appropriate extension for the language.

Is code sent to a server?

No. Formatting happens entirely in your browser.
