About JavaScript Obfuscator
Apply basic obfuscation to your JavaScript code to make it harder to read. The obfuscator renames common variable patterns to short single-letter names, encodes string literals as character code arrays, and wraps the output in an immediately-invoked function expression (IIFE). Useful for light source protection.
How to use
- Paste your JavaScript code into the input panel.
- The obfuscated version appears instantly in the output panel.
- Click Copy to use the obfuscated code in your project.

Frequently Asked Questions
FAQs about JavaScript Obfuscator
Does obfuscation make code truly secure?
No. Obfuscation makes code harder to read but not impossible to reverse-engineer. Determined developers with a debugger can still understand obfuscated JavaScript.
Will the obfuscated code still work?
Yes. The obfuscator preserves runtime behavior — only identifier names and string representations change.
What does encoding strings as char codes do?
String literals are replaced with String.fromCharCode(...) calls, making the original strings less obvious in a static code view.
What is an IIFE?
An Immediately Invoked Function Expression (IIFE) wraps code in a function that runs immediately. It creates a private scope, preventing variable leakage into the global namespace.
Is my code safe?
All processing runs entirely in your browser. No code is ever sent to a server.
