Frequently Asked Questions
Can this deobfuscate arbitrary code?
It handles standard minification and packing well. Heavily obfuscated code (with renamed variables) will be formatted for readability, but original variable names cannot be restored.
Does it support modern JS (ES6+)?
Yes! Our formatter supports the latest ECMAScript standards, including arrow functions, async/await, and classes.
Is my proprietary code safe?
Absolutely. All processing happens locally in your browser. We never upload your scripts to any external server.
