JavaScript Obfuscator Online – Free JS Obfuscation Tool

JavaScript Obfuscator Online is a free web-based tool that allows you to protect your JavaScript code by converting it into an obfuscated and hard‑to‑read format directly in your browser, without installing any software. Obfuscation hides code logic by renaming variables, altering structure, and making scripts difficult to understand or reverse‑engineer.

This tool is ideal for developers, students, and content creators who want to protect their JavaScript code, prevent unauthorized copying, and add an extra layer of security to client‑side scripts.
