It allows the creation of QR codes for various inputs, including active tabs, links, selected text, and user-defined content. The program's ability to operate entirely offline ensures that no data is transmitted over the network, enhancing user security and privacy. Additionally, it remembers previously generated or scanned QR codes for easy access.

The application also supports QR code scanning from multiple sources, such as images, clipboard content, any part of web pages, and even through a webcam.
