How to use the WhatsApp QR Code Generator
Step 1: Enter your WhatsApp number
Choose the country code (India +91 by default) and type your number without spaces or a leading zero.
Step 2: Add a pre-filled message
Optionally write the message customers will see when the chat opens, such as “Hi, I scanned your QR code at the store”.
Step 3: Customise the QR code
Pick the download size and the QR colour. Keep strong contrast with the white background so it scans reliably.
Step 4: Scan to test
Scan the preview with your phone camera to confirm it opens the right WhatsApp chat.
Step 5: Download and print
Download the PNG and add it to menus, flyers, packaging, standees, visiting cards or invoices.
What is a WhatsApp QR code?
A WhatsApp QR code is a regular QR code that contains a wa.me click-to-chat link. Scanning it with any phone camera opens WhatsApp with your number, and, if you set one, a pre-filled message, ready to send.
The QR code is static: it encodes the link directly, so it never expires and needs no third-party redirect service.
Where businesses use WhatsApp QR codes
Restaurants put them on table tents for orders and feedback, retailers on billing counters and shopping bags, D2C brands inside delivery boxes for reorders and support, and real-estate teams on site boards and brochures.
Use a different pre-filled message for each placement (“Hi, I scanned the menu QR”) to see which location brings the most chats.
Tips for a QR code that always scans
Print at least 2 × 2 cm (larger for posters viewed from a distance), keep dark colours on a light background and leave a clear margin around the code. Always test-scan the printed proof before a big print run.
Shorter pre-filled messages produce simpler QR codes that scan faster, so keep the message to one line.
Handle every scan with the WhatsApp Business API
Every scan starts a customer-initiated conversation, and service conversations are free. With Chatbox AI you can greet each scanner instantly with a no-code chatbot, route chats to the right agent in a shared team inbox and follow up later with opted-in broadcasts.

Is this WhatsApp QR code generator free? Yes. The Chatbox AI WhatsApp QR code generator is free with no sign-up, no watermark and no scan limits. The QR code is generated in your browser and encodes a standard wa.me link, so it keeps working indefinitely.
Does a WhatsApp QR code expire? No. This is a static QR code that directly contains your wa.me link, so it never expires and does not depend on any redirect service. It works as long as your number remains registered on WhatsApp.
Can I change the message after printing the QR code? No. Because the message is encoded inside the QR code, changing it means generating and printing a new code. If you need to change messages often, point customers to a chatbot on the WhatsApp Business API and change the bot’s reply instead.
What size should I print my WhatsApp QR code? Print it at least 2 × 2 cm for close-range use such as visiting cards and packaging. For counters and table tents use 4–6 cm, and for posters scanned from a few metres away go larger. Download the 1024 px PNG for print.
Can I use a custom colour for my QR code? Yes. Choose any dark colour for the modules, the default is WhatsApp-style dark green. Keep high contrast against the white background; light colours such as yellow or pale green may not scan reliably.
Is WhatsApp’s own QR code different from this one? The WhatsApp Business app can show a QR code for your profile. This tool creates a wa.me QR code that also supports a pre-filled message, custom colours and a downloadable PNG, and works for API-connected numbers too.
