FAQ

Q. Is my code safe?

A. Yep. Everything stays in your browser. We never see your code—nothing gets uploaded.

Q. What's Beautify vs Minify?

A. Beautify makes code readable by adding indentation and line breaks. Minify does the opposite—removes all whitespace to make files smaller. Use Beautify for debugging, Minify for production.
