Javascript DeObfuscator

A JavaScript DeObfuscator is an online utility designed to transform obscured or minified JavaScript code back into a more readable and understandable format. When developers encounter scripts that have been deliberately scrambled—through techniques such as variable renaming, string encoding, control‑flow flattening, or dead‑code insertion—this tool attempts to reverse those transformations while preserving the original logic and behavior. By pasting the obfuscated code into the input box or uploading a file, users receive a cleaned‑up version that retains proper indentation, meaningful variable names, and clear string literals, making it easier to debug, audit, or learn from the script. The deobfuscator supports many common obfuscation patterns found in web applications, browser extensions, and malicious payloads, though results may vary depending on the complexity of the encoding. It serves as a helpful resource for security analysts, frontend developers, and anyone who needs to inspect JavaScript that has been intentionally hidden from plain sight.
