Obfuscation Details

  • Rename Variables: Replaces variable/function names with hex identifiers (_0x1a2b)
  • Encode Strings: Converts strings to hex escape sequences
  • Minify: Removes whitespace, comments, and unnecessary formatting
  • Makes code harder to read and reverse-engineer

About this tool

Obfuscate and minify JavaScript code to protect your source code. Basic obfuscation with variable renaming and string encoding. JavaScript Obfuscator runs in the browser on DevTools. There is no signup, and your input stays on this device unless the tool explicitly performs a live network lookup.

What this tool does not do

  • JavaScript Obfuscator is a free in-browser utility, not a hosted API. It does not keep server-side history and is not a substitute for production verification in your own stack.

How do I use this tool?
