Frequently Asked Questions

How does scanning a WhatsApp QR code open a chat?

The QR code encodes a standard wa.me universal deep link. When scanned by a phone camera, it immediately opens the WhatsApp application directly to your active chat window.

Do customers need to save my phone number before chatting?

No. The WhatsApp deep link bypasses the need to save your contact in the address book, launching the chat dialog immediately for effortless customer communication.

Does this generator work with WhatsApp Business accounts?

Yes. It works identically with standard personal WhatsApp accounts and WhatsApp Business accounts, supporting automated welcome flows.

Are my phone numbers or custom messages logged on your servers?

No. All QR matrix rendering is performed locally in your web browser memory. Your phone numbers and messages are never stored, tracked, or shared.

Can I change the pre-filled message later?

The QR code is static and directly encodes the message; to update the greeting, simply generate and print a new QR code in seconds for free.
