A general-purpose JavaScript deobfuscator that removes common obfuscation techniques such as array unpacking, proxy functions, expression obfuscation, and hexadecimal identifier renaming. It is available as an npm package, a CLI, and an online web tool at deobfuscate.io.

Use cases

• deobfuscate javascript code
• reverse engineer obfuscated js malware
• undo obfuscator.io transformations
• rename hexadecimal identifiers in javascript
• simplify obfuscated string concatenation and arithmetic
• analyze suspicious javascript from a website

When to choose

• you need to read or analyze obfuscated JavaScript from unknown or malicious sources
• you want a general-purpose deobfuscator handling common techniques rather than one specific tool
• you want both a programmatic npm library and an online web interface

When to avoid

• the code was obfuscated specifically with Obfuscator.io and you can use the more specialized deobfuscator-io tool instead
• you need deobfuscation for languages other than JavaScript
• you expect guaranteed recovery of original source code - obfuscation is not always fully reversible
