Obfuscate JavaScript Code to Protect It
Transform your JavaScript source into a hard-to-read version that still runs identically. The obfuscator renames variables, encodes strings, and adds control flow flattening.
Useful when you need to ship client-side code that you don't want easily reverse-engineered. Adjust the protection level to balance security against file size and performance. A deobfuscation mode is also available for analysis.
Frequently Asked Questions — JS Obfuscator
No. Obfuscation makes code harder to read, not impossible to reverse. Determined attackers can still deobfuscate it. It raises the effort level.
Yes, somewhat. Higher protection levels add more overhead. Test performance after obfuscating to ensure it's acceptable.
The deobfuscator tries to undo common transformations, but it can't perfectly reconstruct the original source. Variable names and comments are lost forever.
