Frequently Asked Questions
Does beautifying change how the JavaScript code runs?
No — beautifying only adds whitespace and formatting for readability. The logic and behavior of the code remain unchanged.
Is my code sent to a server?
No, formatting happens entirely in your browser using JavaScript. Your code is never uploaded or stored.
