Frequently Asked Questions

No, obfuscation makes code difficult to understand but doesn't encrypt it. The code remains executable without a key, just harder to read and reverse-engineer.

There might be minimal performance impact depending on obfuscation settings, but for most applications the difference is negligible.

While technically possible with enough effort, good obfuscation makes reverse-engineering extremely time-consuming and impractical.

Our tool can handle files up to 1MB in size. For larger files, consider splitting your code into modules.
