JavaScript Code Obfuscator
Protect client-side JS logic with variable renaming, hex string encoding, dead code injection, and control flow flattening.
How to Use JavaScript Code Obfuscator
Paste your clean JavaScript code.
Select obfuscation preset (Low, Medium, High).
Download or copy the protected obfuscated script.
JavaScript Code Obfuscator runs 100% client-side in your web browser. Your data, passwords, keys, and files are processed using the Web Crypto API and never transmitted to any server. Zero telemetry, zero storage, zero cloud processing.
Frequently Asked Questions
Does obfuscation replace secure backend authentication?
No! Never place API secrets or sensitive business rules in client-side code, as any client script can ultimately be reverse-engineered.
