Tips for printable QR codes
Choose the Print (900px) size for anything physical, keep the white border (quiet zone) intact, and never print smaller than 2×2 cm. Test-scan from arm's length before mass printing. Want a clickable link instead of a code? Use our WhatsApp link generator, or add a chat button to your website.
