How It Works

This tool applies several obfuscation techniques:
  • Variable Renaming: Changes meaningful variable names to short, meaningless identifiers
  • Function Renaming: Obfuscates function names to hide their purpose and functionality
  • String Concealing: Hides string literals by converting them to array references
  • Control Flow Flattening: Transforms the program's control flow to make it harder to follow
  • Dead Code Injection: Inserts non-functional code to confuse anyone reading the code
  • Comment Removal: Strips all comments from the code to remove hints about functionality

Ideal for protecting your JavaScript code from being easily copied or understood, while maintaining its functionality.

Note: While obfuscation makes code harder to understand, it doesn't provide perfect security. Critical business logic should be moved to server-side code for maximum protection.

Tips

  • Test Your Code

    Always test your obfuscated code before deploying to ensure it works properly

  • Keep Original Version

    Always save your original, readable code for future maintenance

  • Use Source Maps in Development

    For production code, consider generating source maps for debugging

  • Add Comments Later

    All comments are removed during obfuscation; add minimal ones back if needed for production
