Minify and obfuscate JavaScript locally: strip comments, collapse whitespace, mangle names, encode strings, and beautify code.
FAQ
Is my pasted code uploaded anywhere?
No. Minifying, obfuscating and beautifying all run locally in your browser. The code is never saved or uploaded and is cleared on reload, so internal or business code is safe to process.
Why does a parse error appear and can obfuscation be reversed?
Parse errors usually mean the code has syntax errors or uses unsupported syntax, so first confirm it runs locally. Obfuscation is not reversible; beautify only reformats code and cannot restore original names, so keep a source backup.
