  About JavaScript Obfuscation

  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

  Obfuscation Techniques

This tool uses multiple transformation techniques:

  • String encryption and encoding
  • Control flow flattening
  • Identifier renaming
  • Dead code injection
  • Anti-debugging protection
  • Code splitting and restructuring

  Performance Impact

Obfuscation may affect your code:

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

Tip:Test performance after obfuscation and adjust settings as needed.

  Usage Guide

  1. Paste your JavaScript codeoruploada .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. Copythe result ordownloadas a file
  5. Test thoroughlybefore deployment

Pro Tip:Start with medium protection level and increase gradually if needed. Higher protection may impact performance.

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.

    Enhanced CSS Protection:Apply an additional layer of obfuscation specifically designed for CSS embedded within your JavaScript, making it significantly harder to reverse engineer your design.
