Javascript Deobfuscator

Javascript Deobfuscator

Decode and beautify obfuscated JavaScript to make minified or protected code easier to read. This browser-based tool applies common cleanup steps such as hex and unicode escape decoding, string concatenation unwrapping, bracket notation simplification, and JS beautification. For standard formatting of readable code, see our Javascript Beautifier.

What this tool can recover

• Escaped string literals using \x and \u sequences.
• Simple chained string concatenation patterns.
• Bracket-style property access converted to dot notation.
• Re-indented output using js-beautify.

Limitations

Advanced obfuscators may rename variables, encrypt strings, or inject control-flow tricks that cannot be fully reversed automatically. Treat output as a readability aid, not guaranteed original source. Never execute deobfuscated code from untrusted origins. Pair with Javascript Obfuscator when testing how obfuscation affects your own scripts.
