Obfuscate HTML and JavaScript code to protect your source code from being easily read or copied. Choose from light, medium, or heavy obfuscation levels.
The HTML/JS Code Obfuscator by TooliFyra is a free online code protection tool that transforms readable HTML and JavaScript code into obfuscated versions that are difficult to understand, reverse-engineer, or copy. It applies multiple transformation techniques depending on the selected protection level.
The tool runs entirely in your browser — your code never leaves your device, ensuring complete privacy and security for your source code.
Code obfuscation adds a layer of protection against casual code theft and reverse engineering. While not bulletproof, the free JavaScript obfuscator makes your code significantly harder to read and understand, deterring most unauthorized copying and modification attempts.
Web Developers: Protect proprietary JavaScript algorithms and logic from competitors.
Game Developers: Obfuscate client-side game code to prevent cheating.
SaaS Products: Add protection to license verification and authentication code.
Educational Platforms: Protect quiz answers and form validation logic from being easily copied.
TooliFyra provides a free code obfuscator that runs 100% client-side for maximum privacy. No code uploads, no server processing — everything happens in your browser. Choose from three protection levels to match your security needs.
Yes, completely free with unlimited usage. No sign-up or premium features required.
Obfuscation adds a strong layer of protection but is not encryption. Determined attackers with enough time can still reverse-engineer obfuscated code. For maximum security, combine obfuscation with server-side logic.
No, the obfuscated code produces exactly the same output as the original. Only the code structure and naming are changed for readability protection.
Light is best for minor protection with minimal size increase. Medium offers a good balance. Heavy provides maximum protection but results in larger file sizes.
