Protect your JavaScript code by making it unreadable

Frequently Asked Questions

What is JavaScript obfuscation?

JavaScript obfuscation transforms readable code into an equivalent but hard-to-understand version, protecting intellectual property and making reverse-engineering difficult.

Does obfuscation affect performance?

Obfuscated code may be slightly larger and marginally slower, but for most use cases the difference is negligible.

Is obfuscated code secure?

Obfuscation adds a layer of protection but is not encryption. Determined attackers can still reverse-engineer it, so never rely solely on obfuscation for security.
