Download v3.1.0 WinForms (Lightweight)

Obfuscating JavaScript files manually one by one can be time consuming. The desktop GUI tool lets you batch-process entire projects in just a few clicks.

Release Workflow

Download the desktop app when your browser test becomes a repeatable release step

The browser tool is great for quick checks. The desktop workflow is the better fit when you need larger projects, embedded JavaScript support, cross-file consistency, or a generated command line for repeated release automation.
