On the free QR code generator tool provided by pub-trivia.app, the tool's JavaScript bundle size is 363 KB. When the PDF button is clicked, the bundle size increases by 137 KB, totaling 500 KB. The tool is lightweight with no backend, consisting of four tools on four pages: a QR code generator, a scoresheet generator, a round planner, and a team name generator.
The scoresheet generator and team name generator rely on two large dependencies, qrcode and jspdf, respectively. These dependencies are only imported when needed, preventing unnecessary loading of large libraries. The QR code generation process involves downloading a code based on the input URL. The scoresheet generation process creates an A4-size PDF with four QR codes.
Overall, the tool's functionality is achieved without uploading or sending any data to a server, as the data is generated and displayed in the user's browser.
