About deobfuscate.io
deobfuscate.io is a web-based tool that attempts to remove common obfuscation techniques from JavaScript code. Users paste code into an input box, click Deobfuscate, and copy the result from the output panel.
A set of configuration options controls which transformations are applied, including unpacking and removing arrays, handling proxy functions, simplifying expressions and string operations, removing dead branches, beautifying output, and renaming hex identifiers. The homepage describes the tool as covering common techniques only and does not list every technique it handles. If deobfuscation fails, an error message appears and the homepage directs users to the browser console for more detail.
