WhatsApp QR Code Generator
Enter a phone number and an optional pre-filled message, then generate a QR code that opens a WhatsApp chat when scanned — free, private, and processed entirely in your browser.
About the WhatsApp QR Code Generator
A WhatsApp QR code lets someone start a chat with you instantly — scan it, and WhatsApp opens with your number already entered and, if you choose, a message pre-filled and ready to send. No saving a number to contacts first, no typing a greeting.
This tool encodes your phone number (and an optional pre-filled message) into a wa.me link — WhatsApp's own official link format for starting a chat. Scanning it opens WhatsApp directly, on the phone's app if installed or WhatsApp Web otherwise. Everything is generated locally in your browser; your number is never sent to a server.

Frequently Asked Questions
What happens when someone scans this code?
WhatsApp opens directly with a chat to your number already started — with your pre-filled message ready to send, if you added one.
Do I need a business WhatsApp account?
No. This works with any regular WhatsApp number, personal or business — it uses WhatsApp's own wa.me link format.
What format should I use for my phone number?
Full number in international format including country code (e.g. 1 for the US), without spaces, dashes, or a leading '+' or '00'.
Is my phone number uploaded anywhere?
No. The QR code is generated entirely inside your browser — nothing is sent to a server.
