JavaScript Obfuscator

Protect your JavaScript code by obfuscating variables, functions, and strings for enhanced security and code protection.

Examples: +10 days, tomorrow, 2024-12-31, +5 hours
Code will only work on specified domain

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");
