How WhatsApp Click-to-Chat QR Codes Work
Standardized, officially supported WhatsApp deep linking protocol.
WhatsApp provides a universal deep link format called Click to Chat (https://wa.me/<number>). When encoded into a QR code, any smartphone camera recognizes it as a direct action link that launches WhatsApp with your number pre-addressed.

Everything you need to know about generating and using WhatsApp QR codes.
Do WhatsApp QR codes expire?
No. WhatsApp QR codes generated with ChatGrow encode standard WhatsApp Click-to-Chat URLs (https://wa.me/...). They never expire as long as your phone number remains active.
How do customers scan a WhatsApp QR code?
Customers can open their native smartphone camera (iOS Camera or Android Google Lens/Camera) and point it at the QR code. A notification banner pops up instantly, opening the WhatsApp conversation directly.
Can I print this QR code on flyers, packaging, and store counters?
Yes! Our generator exports ultra-sharp 1024x1024 high-resolution PNG files that are print-ready for product boxes, delivery slips, retail counters, event banners, and business cards.
Is my phone number or message stored on any server?
No. The QR code is generated 100% locally in your browser using client-side JavaScript. Your phone number and pre-filled message are never sent to or stored on ChatGrow servers.
Can I pre-fill a custom welcome message in the QR code?
Yes. You can enter an optional message like 'Hi! I want to inquire about your product pricing'. When the customer scans the code, that message is automatically inserted into their chat input box ready to send.
