JavaScript Deobfuscator and Unpacker
The Unreadable option is disabled by default, because it uses data from JS Nice. This cannot be done with JavaScript. You need to install UserScript de4js_helper.user.js to enable it.
Install one of the following links:
* de4js helper doesn't work offline.
- Works offline.
