Is my JavaScript code safe when using this formatter?

Absolutely. All formatting is performed entirely in your browser using client-side JavaScript. Your code never leaves your device or gets sent to any server.

Can this format heavily minified production JavaScript?

Yes, the formatter can handle any minified JS including webpack bundles, uglified code, and compressed libraries, restoring full readability instantly.

Will formatting break or change my JavaScript functionality?

No, the formatter only modifies whitespace, indentation, and line breaks. Your code's logic, variables, and execution remain completely unchanged.

Can I use this to understand obfuscated JavaScript?

Formatting helps by restoring structure, but obfuscated variable names and logic will remain. It's the first step in code analysis, best combined with debugging tools.
