JavaScript Obfuscator
Protect your JavaScript code by obfuscating variables, functions, and strings for enhanced security and code protection.
How it works:
- Variable Obfuscation: Replaces variable names with random strings
- Function Obfuscation: Renames function names to random identifiers
- String Obfuscation: Converts string literals to encoded format
- Comment Removal: Removes all comments and whitespace
- Domain Locking: Restricts code execution to specific domains
- Expiration: Sets time-based expiration for the obfuscated code
Example Input:
function greetUser(name) { var message = "Hello, " + name + "!"; alert(message); return message; } greetUser("World");
