JavaScript Obfuscator
Obfuscate JavaScript code to make it harder to read and reverse-engineer.
Obfuscate JavaScript
Transform your code to make it harder to read and copy while keeping it functional.
How this JavaScript Obfuscator works
This obfuscator transforms JavaScript code to make it harder to read while preserving functionality. The tool applies several techniques: variable renaming replaces descriptive names with meaningless identifiers like _0x1a2b, string encoding converts literal strings to hex escape sequences, and optional dead code insertion adds non-functional statements.
Users can enable or disable each obfuscation technique independently. The output is also minified by removing whitespace and condensing the code onto fewer lines. While obfuscation is not true security, it raises the barrier for casual code copying.
All transformation happens client-side in your browser. For production use, consider this a deterrent rather than protection - determined attackers can still reverse-engineer obfuscated code with sufficient effort.
