Code beautifier FAQ

Which languages are supported?

HTML, CSS, JavaScript, JSON, C, C++, C#, Java, Swift, Kotlin, Go, Rust, PHP, SQL and XML. HTML/CSS/JS/JSON get full pretty-printing; the C-family and others get brace-aware re-indentation, and every language is syntax-highlighted.

Is my code uploaded anywhere?

No — formatting and highlighting run 100% in your browser, so your code never leaves your device. Safe for proprietary or sensitive code.

Can I minify as well as beautify?

Yes. Minify compresses JSON, CSS and HTML; for other languages it trims trailing spaces and collapses blank lines.

Is it free?

Completely free, no sign-up, no limits, no watermark.
