Frequently Asked Questions

Does this fully reverse obfuscation back to the original source?

It can undo common obfuscation patterns like renamed variables and packed code, but heavily obfuscated code may not fully restore original names or structure.

Can I use this on production or third-party scripts?

Yes, it's commonly used to inspect and debug minified or obfuscated third-party or legacy scripts.

Will it restore the original variable names?

No, original variable names are lost during obfuscation, so the tool generates readable generic names instead.
