JavaScript Obfuscator

JavaScript obfuscation transforms readable source code into a form that is difficult for humans to understand while remaining functionally equivalent. It renames variables, encodes strings, and restructures code.

No. Obfuscation makes code harder to read and reverse-engineer, but a determined attacker can still deobfuscate it. It raises the effort required, but is not true encryption.

This tool performs safe transformations: renaming local variables, encoding string literals, and inserting dead code. It should preserve functionality, but always test your obfuscated code.

Variable renaming (replaces variable names with random strings), string encoding (converts strings to hex escape sequences), dead code injection (adds non-functional code), and basic control flow changes.

No. All obfuscation happens in your browser. Your code is never uploaded or transmitted anywhere.
