Abstract

This project addresses the need for accessible and cost-free QR code generation. It provides a straightforward online tool allowing users to easily create QR codes without incurring any charges, alongside open-source availability for further development and customisation.

Concept

QR codes have become ubiquitous, facilitating rapid access to information via mobile devices. However, many online QR code generators require payment or impose limitations on usage. This project aims to remove those barriers by offering a completely free resource for generating QR codes. The underlying technology leverages the kjua library, ensuring robust and reliable QR code creation.

Process Development

The website interface is designed with user experience in mind. As the user inputs text, a live preview of the generated QR code appears on the left-hand side of the screen. This allows for immediate visual confirmation before downloading. On the right, the input text is displayed clearly. Users can then download their created QR code in two formats: a PNG file (with a transparent background) and an SVG file – both available at no cost. The project’s source code is openly accessible on GitHub (https://github.com/zumatt/qrcode), encouraging community contribution and transparency.

Note

This QR code generator is provided as a free resource, built upon the kjua library. Users are welcome to explore the open-source repository for further insights into its functionality or to contribute to its ongoing development.
