How do I prepare a QR code for my card or stand at an exhibition? — answered by Engineer Saeed Baatiah
Use the free QR generator on this site: pick the content type — a link, a WhatsApp number, or a vCard — then add your logo in the middle, choose your colours, and export as SVG or PDF if the code is going on a large printed panel, because those two formats do not lose quality when scaled up, unlike PNG. No sign-up, no watermark. The practical tip: point the code straight at WhatsApp rather than at your website — it saves whoever scans it two steps.
