QR generator
Choose a QR type, fill only the fields that belong to that payload, then review the live preview and validation messages before downloading. The generator runs in the browser, so the text, contact details, WiFi password, logo image, and payload preview are not sent to a QRIN server by this app.
QRIN supports URLs, plain text, WiFi credentials, WhatsApp links, email drafts, vCards, and calendar events. Each QR type uses structured fields so the generated payload is easier to review before download.
Use strong foreground/background contrast, keep logos small, prefer Q or H error correction when adding a logo, and test printed QR codes on both iOS and Android devices before using them in public materials.
