A WhatsApp QR code links directly to a chat with your number, complete with an optional pre-filled message. Scanning it opens WhatsApp and starts the conversation immediately — no need to save a contact first. It's ideal for customer support, restaurants, retail counters, and small businesses that want faster inquiries.

- Choose WhatsApp. Select the WhatsApp option from the generator.
- Enter your number. Add your WhatsApp number and an optional pre-filled message.
- Customize (optional). Add colors, a logo, or a custom shape to match your brand.

Frequently asked questions
Is the WhatsApp QR code generator free?
Yes. Creating WhatsApp QR codes and downloading them as JPG, PNG or SVG is completely free with no sign-up, including colors, shapes and an image logo. PDF, EPS and transparent-background downloads are free too, up to 4096 px; Pro adds up to 50 editable dynamic codes and scan activity.
Do I need a WhatsApp Business account?
No. It works with any personal or WhatsApp Business number.
Can I pre-fill a message for people who scan it?
Yes. You can add a default message that appears in the chat box automatically.
Is my phone number stored anywhere?
No. The QR code is generated locally in your browser and nothing is sent to a server.
Do I need to include the country code in my number?
Yes. Always enter your number in full international format, including the country code, so the QR code opens correctly for anyone scanning it, wherever they are.
What happens if someone doesn't have WhatsApp installed?
On mobile, scanning usually prompts them to install WhatsApp or opens WhatsApp Web in a browser instead. Without either, the chat link simply won't open a conversation.
Can I use this for a WhatsApp group instead of a single number?
This generator is built for one-to-one chat links tied to a single number. For group invites, you'd need to convert a WhatsApp group invite link into a QR code using the generic link/URL QR type instead.
Will the pre-filled message send automatically?
No. The message appears typed into the chat box ready to send, but the person scanning still has to tap send themselves — nothing is sent on their behalf.
Best practices for WhatsApp QR codes
- Include the full country code with your number (e.g. +1 for the US) — a WhatsApp QR code without it can fail to open a chat correctly for scanners in other countries.
- Write a short, specific pre-filled message like "Hi, I'd like to ask about your menu" instead of a generic "Hello" — it lowers the barrier for customers to actually send it.
- Place the code somewhere people already have their phone out: a receipt, a table tent, checkout counter, or packaging insert, rather than a wall poster they'd need to walk up to.
- Label the code clearly with "Chat with us on WhatsApp" or similar text — an unlabeled QR code gets ignored far more often than one with a clear call to action.
- Re-test the code periodically if you ever change business numbers; an old WhatsApp QR code will open a chat with a number that's no longer monitored.
Where WhatsApp QR codes work best
Small businesses without a call center use WhatsApp QR codes as a low-friction customer service channel — a code on a storefront window or delivery box lets a customer ask about order status or availability in seconds, without hunting for a phone number or filling out a contact form. Restaurants print them on table cards so guests can message ahead for reservations or ask about dietary options before ordering.
Real estate listings and market stall vendors use them so a passerby can immediately message a question rather than calling and possibly getting voicemail. Event organizers place WhatsApp QR codes on flyers and lanyards to create a direct RSVP or support line for attendees, which tends to get higher response rates than an email address because most people already have WhatsApp open on their phone.
