What is this?
JavaScript Obfuscator is a powerful free obfuscator for JavaScript, containing a variety of features which provide protection for your source code. This tool transforms your original JavaScript source code into a new representation that's harder to understand, copy, re-use and modify without authorization. The obfuscated result will have the exact functionality of the original code.
How does the obfuscation work?
Through a series of transformations, such as variable / function / arguments renaming, string removal, and others, your source code is transformed into something unreadable, while working exactly as before.
How to use this tool?
Just paste your code and click on "obfuscate".
So, it is like UglifyJS, Closure Compiler, etc?
Yes and no. While UglifyJS (and others minifiers) does make the output code harder to understand (compressed and ugly), it can be easily transformed into something readable using a JS Beautifier. This tool prevents that by using various transformations and "traps", such as self-defending and debug protection.
