Frequently asked questions
What phone number format should I use?
Include the full international format with country code (e.g. +1 555 123 4567); the tool strips formatting characters automatically.
Is the pre-filled message required?
No, leaving it empty simply opens a blank chat with your number.
Is my data uploaded when I use this tool?
For most FlyUtils tools, no. Processing happens in your browser with JavaScript. If a tool ever needs a server, that will be stated clearly on the page.

Yes. WhatsApp QR Code Generator is free, with no sign-up and no artificial usage caps for normal personal and work use.
Does WhatsApp QR Code Generator work on mobile?
