WhatsApp QR Code Generator: Create a Free QR Code for Your Number
Create a WhatsApp QR code for your number with a pre-filled message and the WhatsApp logo, download it as PNG or SVG, and learn where to put it.
A WhatsApp QR code holds a wa.me link to your number. Customers scan it with their phone camera and a chat with you opens straight away, without saving your number. Enter your number with the country code and a pre-filled message in the generator on this page, then download the code as PNG for screens or SVG for print at any size.

The generator runs in your browser and does not send your number or message to any server.
02How does a WhatsApp QR code work?
The code holds the direct WhatsApp link to your number (wa.me), plus a pre-filled message if you add one. Customers need no special app: the phone camera reads the code directly.
- The customer points the phone camera at the code.
- A WhatsApp link appears, and they open it with a tap.
- A chat with your number opens, with the message already typed.
- They tap send, and the conversation starts on your side.
The QR code that the WhatsApp app generates also works, but its design is fixed and it stops working if you reset it in settings. The wa.me code from this generator stays valid as long as your number doesn't change.
03Where to put your WhatsApp QR code
- Shop window and checkout: "Scan to order on WhatsApp".
- Packaging and the thank-you card inside the order: for reorders and after-sales service.
- Restaurant menus and tables: for orders and bookings.
- Printed ads, billboards and brochures.
- Invoices and delivery receipts: for order questions.
- Business cards and exhibition booths.
04Tips so the code scans the first time
| Use | Smallest suggested size | Note |
|---|---|---|
| Card or sticker on packaging | 2.5 × 2.5 cm | Scanned from close up |
| Menu or table | 3 to 4 cm | Leave a white margin around the code |
| Poster or shop window | 10 cm or more | Size is roughly the scanning distance ÷ 10 |
| Billboard or outdoor ad | Depends on distance | Use SVG so it stays sharp |
- High contrast: a dark colour on a light background, never inverted.
- Don't crop the white margin around the code; the generator adds it automatically.
- A shorter message means a simpler code that scans faster.
- Scan the code with more than one phone before printing.
Write the number with the country code and without a leading zero or +, otherwise the code opens a chat with the wrong number.
05See which QR code brings customers
Use a different pre-filled message for each placement, such as "Hi, from the menu" and "Hi, from the order card". From the first message you know which code brings more chats, and where to invest in print.
And when the chats pile up, the Modeer 360 unified inbox routes them to your team, while the AI agent replies within seconds, around the clock.
Key takeaways
- The code holds a wa.me link to your number and opens the chat without saving it.
- Write the number with the country code, without a leading zero or +.
- SVG for print at any size, PNG for screens and social media.
- A different pre-filled message per placement shows which code brings customers.
Frequently asked questions
Is a WhatsApp QR code free?
Yes. The code holds a public wa.me link, and the generator on this page is completely free, with no watermark.
Does the QR code expire?
No. The code is static and holds your link directly, so it keeps working as long as the same number is on WhatsApp. If you change numbers, create a new code.
Does it work with WhatsApp Business and the WhatsApp API?
Yes. wa.me links open a chat with any WhatsApp number: the regular app, the WhatsApp Business app, or a WhatsApp Business API number.
Which is better for print: PNG or SVG?
SVG for print, because it stays sharp at any size; PNG for social media, websites and presentations.
Can phones still read the code with the WhatsApp logo in the middle?
Yes. When you add the logo, the generator raises error correction to Q, which survives losing up to 25% of the code, while the logo covers only about 5%. Still, scan it with two phones before printing.
