Variable Name Recovery
Attempts to restore obfuscated variable names to meaningful names based on context and usage patterns.
JavaScript Deobfuscator Tool
Reverse obfuscated JavaScript code and restore it to a readable format. Best-effort restoration with multiple techniques.
Note: This is a best-effort deobfuscation tool. Results depend on the obfuscation method used. Complex obfuscation may not be fully reversible.
What Can Our Deobfuscator Do?
String Decoding
Detects and decodes encoded strings like hex, Unicode escapes, Base64, and other encoding schemes.
Control Flow Simplification
Simplifies flattened control flow and restores original code structure for better readability.
Code Formatting
Adds proper indentation and formatting to make the code human-readable again.
What is JavaScript Deobfuscation?
JavaScript deobfuscation is the process of reversing obfuscation techniques to restore obfuscated JavaScript code to a more readable and understandable format. While obfuscation makes code difficult to understand, deobfuscation attempts to recover the original code structure.
How JavaScript Deobfuscation Works
Our deobfuscator uses several techniques to restore code:
- Variable Name Recovery: Analyzes variable usage patterns to assign meaningful names
- String Decoding: Detects encoded strings (hex, Unicode, Base64) and decodes them
- Control Flow Analysis: Identifies and simplifies complex control flow structures
- Code Formatting: Adds proper indentation and line breaks
Limitations of Deobfuscation
It's important to understand that deobfuscation is not always 100% successful. Some obfuscation techniques are designed to be irreversible, and heavily obfuscated code may not be fully recoverable. However, our tool provides best-effort restoration that can significantly improve code readability in many cases.
