FAQ

Common questions about Code Deobfuscator.

What types of obfuscation does this tool decode?

This tool specializes in URL-encoded (percent-encoded) obfuscation, which is one of the most common ways code is hidden in web payloads, scripts, and logs. It converts sequences like %20 and %3D back into readable characters.

Is my code sent to a server?

No. All decoding happens locally in your browser using JavaScript. Your code never leaves your device, making it safe for sensitive or proprietary snippets.

Can I use this for security analysis and reverse engineering?

Absolutely. Security analysts and reverse engineers use this tool to quickly reveal hidden payloads, decode suspicious scripts, and understand obfuscated code without writing custom scripts.

What if the output still looks obfuscated?

Some code uses multiple layers of obfuscation. If the output still contains encoded characters, paste it back into the tool to decode additional layers.
