How to make a WhatsApp QR code
To make a WhatsApp QR code, use the chat link format https://wa.me/ followed by your number in international format with digits only, for example https://wa.me/15551234567. Add ?text= and a message to prefill the first message. This page already has an example in the URL box: change the number, and the QR code updates. Download it as PNG or SVG. Scanning it opens a chat with you.
The wa.me link format
| Part | Example | Notes |
|---|---|---|
| Base | https://wa.me/ | Always the same |
| Number | 15551234567 | Country code and number, digits only: no plus sign, spaces, brackets or dashes |
| Message (optional) | ?text=Hello%20there | Percent-encoded text; a space is %20 |
Why a WhatsApp QR code works well
- Customers already use WhatsApp, so starting a conversation takes one scan.
- No number to type, which removes the most common mistake.
- Prefilled text tells you where the enquiry came from, for example Table 12 or Poster in the station.
- It works with WhatsApp Business numbers as well as personal ones.
Tips
- Use a business number if the code will be public: anyone can scan it.
- Test the code on iPhone and Android, with and without WhatsApp installed; without the app the link opens a web page that suggests installing it.
- Keep the prefilled message short and put the campaign name in it.
Encoding the message
The message must be percent-encoded: a space is %20, a line break is %0A and an ampersand (&) is %26. If you want to encode a longer message safely, use the URL encoder tool first and paste the result after ?text=.
Private by design
The code is drawn by your browser on your own device. What you type, including passwords and contact details, is never sent to a server, and the finished image is yours with no watermark and no expiry.
