Does obfuscation change how my code functions?

No, the logic remains identical, but the structure is transformed to be difficult for humans to read.

Can I reverse the obfuscation process?

Obfuscation is a one-way transformation. You should always keep your original source code for future updates.

Will obfuscation affect my application's performance?

While highly obfuscated code may have a negligible impact on execution speed, it is generally optimized for production use.

What is the difference between minification and obfuscation?

Minification primarily removes whitespace and shortens variables to reduce file size, while obfuscation adds layers of complexity to hide the code's intent.

Is my code stored on your servers?
