  About JavaScript Obfuscation

If the JS is too large, split it or try minifying it. Maximum 28000 characters.

  Why Obfuscate?

Code obfuscation helps protect your JavaScript by:

  • Preventing reverse engineering
  • Discouraging unauthorized use
  • Protecting intellectual property
  • Reducing piracy risks
  • Making tampering more difficult

  Nebula Obfuscation

Nebula is a powerful client-side JS obfuscator to protect your code.

  Performance Impact

Obfuscation may affect your code:

  • Slightly increased file size
  • Minimal runtime overhead
  • Initial parsing may be slower
  • Some optimizations may be hindered

  Usage Guide

  1. Paste your JavaScript code or upload a .js file
  2. (Optional) Paste your CSS into the dedicated CSS input field for protection.
  3. Obfuscate the entire code (which will now include your embedded CSS) using JavaScript Obfuscator.
  4. Copy the result or download as a file
  5. Test thoroughly before deployment

Pro Tip: This lite method is quick but offers less robust protection than full obfuscator.

  Premium Features Explained

Upgrade to premium for advanced protection capabilities:

    Domain Lock: Restrict your obfuscated code to run only on specific domains you define. Essential for licensing and preventing unauthorized use on other websites.

    Expiration Date: Set a precise date after which your obfuscated code will stop functioning. Ideal for trial versions, temporary licenses, or time-sensitive projects.

    CSS Protection: Protect your CSS by embedding it in your JavaScript to protect your design.
