How to Create a WhatsApp QR Code That Opens a Chat

A WhatsApp QR code lets someone start a chat with you by scanning a code — no need to save your phone number first. This is useful for businesses, freelancers, events, and anyone who wants to make it easy for people to reach them on WhatsApp.
Who Needs This: Small business owners who want customer inquiries via WhatsApp. Freelancers putting a QR code on business cards. Event organizers who want attendees to message for information. Restaurants taking orders via WhatsApp. Anyone tired of sharing their phone number verbally.
How It Works: The QR code contains a WhatsApp API URL: `https://wa.me/[phone number]?text=[message]`. When scanned, it opens WhatsApp on the user's phone with a pre-filled message. The user just taps Send. They do not need to save your number first.
What I Tested: I created a QR code for a test number (+44 7700 900000) with the message 'Hello, I saw your website'. I scanned it with an iPhone 14 (WhatsApp installed) and a Samsung Galaxy S23. Both phones opened WhatsApp within 2 seconds with the chat pre-loaded and the message ready to send.
Step-by-Step: (1) Open the [WhatsApp QR Code Generator](/qr-tools/whatsapp-qr). (2) Enter your phone number with country code (no spaces or dashes, e.g., +447700900000). (3) Optionally type a pre-filled message (e.g., 'Hello, I would like to inquire about...'). (4) Click Generate. (5) Download as PNG or SVG.
One Limitation: The recipient must have WhatsApp installed. If they do not have WhatsApp, the link will prompt them to download it. Also, the phone number must include the full international country code — local formats without the country code will not work.
Common Mistake: Including spaces, dashes, or parentheses in the phone number. The wa.me URL format requires a continuous string of digits with the plus sign. Example: +447700900000 is correct. +44 7700 900 000 or (44) 7700-900000 will fail.
Privacy: The QR code is generated entirely in your browser. Your phone number is processed locally and never sent to our servers. We have no access to the number you enter.
Next Step: If you want a QR code that opens a WhatsApp group instead of a private chat, you will need to create a group invite link first (WhatsApp Settings → Groups → Invite to Group via Link), then encode that link using the [URL QR Code](/qr-tools/url-qr) tool.
