Why Choose ObfuscatorJS?

Enterprise-grade protection, zero compromises

🔒

String Encryption

All string literals are encrypted using Base64 encoding and rot13, making them unreadable at a glance.

🌀

Control Flow Flattening

Code logic is scrambled into complex state-machine patterns that are nearly impossible to trace manually.

🧬

Dead Code Injection

Fake code snippets are injected to confuse decompilers and make reverse engineering extremely time-consuming.

Instant Processing

Your code is obfuscated in milliseconds on our servers with no file size limits for typical projects.

🛡️

Identifier Renaming

Variables, functions, and class names are replaced with meaningless hex identifiers.

🔑

Split Strings

Long strings are split into chunks and reassembled at runtime, defeating pattern recognition tools.
