Project Overview:

The QR Code Generator is a web-based application that allows users to convert any text, URL, email, or phone number into a QR code. Users can then scan the QR code with their smartphone camera or QR scanner apps to access the embedded data.

The project is useful in many domains—business cards, Wi-Fi sharing, event invites, digital menus, etc. It's a great mini project to learn frontend interactivity and external library integration.
