About This Tool
The JS Obfuscator tool, powered by javascript-obfuscator, provides professional-grade source code protection. It supports various obfuscation strategies, including control flow flattening, string array encryption, dead code injection, self-defending, debug protection, and renaming global variables. Choose from presets ranging from "Low" to "High Intensity," or manually adjust granular parameters in Advanced Settings. All obfuscation is done locally in the browser; your source code is never uploaded.
