How to use WhatsApp QR Generator online, free

Create a QR code that, when scanned, opens a WhatsApp chat directly with your number (and optionally a pre-filled message) - useful for businesses wanting customers to start a WhatsApp conversation instantly from a poster, receipt, or business card, without manually saving a contact first.

QR and barcode jobs fail in the real world when contrast is low, the print is tiny, or the payload is longer than it needs to be. Test a scan before you print a stack.

Short answers

Does the scanner need to already have my number saved as a contact?

No - that's the main benefit; the QR code links directly to a chat with your number even if the scanner has never saved you as a contact.

Can I include a pre-filled greeting message?

Yes - typically you can set an initial message that's pre-filled in the chat, which the scanner can send as-is or edit before sending.

Does the scanner need WhatsApp installed for this to work?

Yes - scanning the code opens WhatsApp specifically, so the scanner's device needs the app installed for the link to work as intended.
