How to make a WhatsApp QR code
A WhatsApp QR code opens a chat with your number the moment someone scans it — no saving your contact first. It is ideal for support, bookings and sales: on a flyer, receipt, shop window or website, one scan starts the conversation.
Use a wa.me link with your number in international format (and an optional pre-filled message), style the code and download a PNG or SVG. It is a static code that works forever with no account.
Tips for a great QR code
- Your number in full international format (no + or spaces in the link)
- An optional pre-filled message to lower the barrier
- A prompt like “Scan to chat on WhatsApp”
- Your brand colours with clear contrast
- A logo in the centre with high error correction
Tip: Use the wa.me/<number> format — e.g. wa.me/15551234567, no plus sign.
Frequently asked questions
How do I create a WhatsApp QR code?
Build a wa.me link with your number in international format — for example https://wa.me/15551234567 — paste it into the generator, and download the code. Scanning it opens a WhatsApp chat with you.
Can I add a message that is ready to send?
Yes — append a pre-filled text to the link (wa.me/15551234567?text=Hi). When someone scans, the chat opens with that message typed in, ready to send.
Do customers need to save my number first?
No — that is the point. The code opens the chat directly, so there is no need to add you as a contact before messaging.
Is this QR code generator free?
Yes — CalculatorAI's QR code generator is completely free. Create, customise and download as many static QR codes as you want as PNG or SVG, with no signup, no watermark and no scan limit. Static codes never expire. A free account adds dynamic (editable) codes with scan analytics.
Do the QR codes expire?
Static QR codes never expire — the data is encoded in the code itself, so they keep working forever with no account and no fees. Dynamic codes, which you can edit after printing and track, stay live as long as your free account is active.
Need an editable code with scan tracking?
Static QR codes are free forever and never expire. Want to change the destination after printing and see how many people scan — from where and on what device? Create a dynamic QR code and track every scan in the QR Codes dashboard.
