JavaScript Obfuscator
Obfuscate JavaScript to make it harder to read, using real AST-based transformation.
Obfuscation makes code harder to read, not secure — anything that runs in a browser can still be inspected and eventually reverse-engineered; don't rely on this to hide a real secret (like the password check above, which is obfuscated but not actually protected). Runs entirely in your browser; nothing you type is sent anywhere.
What is JavaScript Obfuscator?
Paste JavaScript and get an obfuscated version — variable names mangled, structure rewritten — using a real AST-based obfuscation engine, not a naive find-and-replace that could easily break the code's meaning.
FAQ
No — obfuscation only makes code harder to casually read, not impossible to reverse-engineer. Anything that runs in a browser can be inspected and eventually understood; never rely on obfuscation to protect a real secret like an API key or password check.
It should — the transformation preserves behavior — but always test obfuscated output before shipping it, the same as with any code transformation.
