JavaScript Deobfuscator

Convert obfuscated JavaScript back to readable code

Deobfuscate JavaScript Code

Obfuscated JavaScript is intentionally made difficult to read. Our deobfuscator reverses common obfuscation techniques, transforming scrambled code into something more readable and understandable. Useful for analyzing scripts and debugging issues.

What Gets Deobfuscated

The tool handles various obfuscation techniques including encoded strings, variable name mangling, and code restructuring. While complete deobfuscation is not always possible, the result is typically much more readable than the original.

Code Analysis

Understand what a script does before running it. Debug issues in minified or obfuscated third-party code. Learn from existing JavaScript implementations. Analyze scripts for security review.
