Quick start Four presets String array + base64 or rc4 Control flow flattening Dead code injection Numbers to expressions Rename globals Seed for deterministics

How the

tool works The interface is simple: you paste the JS code into the input field, select a preset and optionally adjust options. You click Obfuscate and after a while you get the result, which you can copy to the clipboard or download as a .js file. The tool also includes a quick Ctrl or Cmd + Enter keyboard shortcut that launches the process without reaching for the mouse.

• Paste the codeinto the input field and make sure it does not contain any unclosed comments.
• Presetselect according to the purpose: from low to maximum.
• Adjustoptions such as string array, base64 or rc4 encoding, flow flattening, dead code injection, numeric expressions and global renaming.
• Runobfuscation and use the Copy result or Download buttons.

A heuristic restart mechanism is available for common parser errors. If an Unexpected token problem occurs in your code, the tool will first try to remove comments and multiple blank lines and reprocess.

Obfuscation Presets balance code concealment, file size, and potential performance impact. The choice depends on your environment, performance budget, and how difficult you want to make code analysis. Below is a comparison of what goes into each level according to the tool's capabilities.
