WhatsApp QR code generator: free, instant, customisable
A WhatsApp QR code is the fastest way to move offline customers into a WhatsApp conversation. Scan it with any phone camera and WhatsApp opens with your number selected and any pre-filled message ready to send. They work brilliantly on packaging, posters, business cards, restaurant menus, event signage and printed ads.
This guide covers how WhatsApp QR codes work, where to generate one, the pre-filled message format, and the highest-converting use cases.
How WhatsApp QR codes work
Under the hood, a WhatsApp QR code is just a QR-encoded version of a `wa.me` URL like `https://wa.me/919876543210?text=Hello`. When a customer scans it with their phone camera, the phone opens WhatsApp with your number selected and (optionally) a message pre-filled in the chat input. No app to install — works on every modern phone.
The wa.me URL format
Base: `https://wa.me/{phone}`. Pre-filled message: add `?text={url-encoded-message}`. Example: `https://wa.me/919876543210?text=Hi%20I%20saw%20your%20menu%20and%20want%20to%20order`. The number must be in international format without `+` or spaces. The message gets pre-filled — the customer still has to press Send.
Where to generate a WhatsApp QR code
LandinChat's free WhatsApp Link Generator at /whatsapp-tools/whatsapp-link-generator creates both the `wa.me` link and the QR code in one click — with your pre-filled message. Download as PNG or SVG. No signup. Use it on packaging, menus, posters, ads, business cards.
High-converting use cases
Restaurant menus (scan to order on WhatsApp). Real estate site signage (scan to book a visit). Retail packaging (scan to register warranty / get manual / leave review). Event check-in (scan to receive itinerary). Print ads (replace 'call us' with 'WhatsApp us'). Business cards (faster than typing a number).
Tracking scans
Vanilla wa.me QR codes don't track scans. To measure, route through a short-link with analytics (e.g. Bitly, or LandinChat's tracked links) before redirecting to wa.me. You get scan counts, geography, device — plus the conversation still lands in your WhatsApp inbox.
Frequently asked questions
How do I generate a WhatsApp QR code for my business?
Use the free LandinChat WhatsApp Link Generator — enter your number and an optional pre-filled message; download the QR as PNG or SVG.
Can a WhatsApp QR code include a pre-filled message?
Yes. Append `?text=Your%20message` to the wa.me URL before encoding. The customer sees the message in the chat input ready to send.
Do WhatsApp QR codes expire?
No. As long as your WhatsApp number is active, the QR code keeps working — print once, use forever.
Can I track scans on a WhatsApp QR code?
Not directly — wa.me has no built-in analytics. Route through a tracked short-link first to count scans.
