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
- Paste your JavaScript code or upload a .js file
- (Optional) Paste your CSS into the dedicated CSS input field for protection.
- Obfuscate the entire code (which will now include your embedded CSS) using JavaScript Obfuscator.
- Copy the result or download as a file
- Test thoroughly before deployment
Pro Tip: Start with medium protection level and increase gradually if needed. Higher protection may impact performance.
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.
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.

Frequently Asked Questions
Q: Is my code sent to your servers?
A: No! All processing happens locally in your browser.
Q: Can obfuscated code be reversed?
A: While extremely difficult, determined attackers with enough time and resources might partially reverse engineer it.
Q: Will obfuscation break my code?
A: It shouldn't when using default settings. Always test thoroughly after obfuscation.
