What is JavaScript deobfuscation?

JavaScript deobfuscation is the process of reversing code obfuscation techniques to make the source readable again. This includes decoding hex/unicode strings, unpacking eval wrappers, recovering string arrays, and beautifying minified code.

Is this tool safe to use with malicious JavaScript?

Yes. This tool never executes the JavaScript code. All deobfuscation is performed using string manipulation and regex parsing entirely in your browser. No code is sent to any server.
