Frequently Asked Questions About QR Codes
What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that stores text, a link or contact info in a square pattern. Scanning it with a phone camera instantly opens the stored information.
How does a WhatsApp QR code work?
The QR encodes a wa.me link. When someone scans it with their phone camera, WhatsApp opens a chat with your number and your prewritten message ready to send.
How do I create a QR code?
Type your number with the country code, optionally add a greeting, and click "Generate QR Code". The code is created instantly — you can view, copy or download it.
How should I format my number?
Use the full international format with country code, without + or 00. Example: 15551234567 for the US, 447700900000 for the UK.
Is the QR tool free?
Yes, it is completely free. No sign-up, account or credit card required, and you can generate as many QR codes as you like.
How long is my QR code valid?
The QR you generate is a static link — it never expires. It keeps working for as long as your WhatsApp number is active.
Can I use the QR code commercially?
Yes. You can freely use the generated QR code on menus, packaging, ads, storefronts and any commercial material.
Can I download or print the QR code?
Yes. Use "Download QR" to save the PNG image, then print it in high resolution on posters, labels and flyers.
Where is a QR code scanned?
With your phone camera app or any QR reader. Modern iOS and Android cameras detect QR codes automatically.
Static vs dynamic QR codes — what is the difference?
A static QR embeds the link directly and cannot be changed. A dynamic QR uses a redirect, so the destination can be updated later and scans can be tracked. This tool creates static QR codes.
Are QR codes safe?
The QR itself only carries a link — safety depends on where that link goes. Here, the code only contains the wa.me link that opens your WhatsApp chat.
Does a QR code work offline?
Scanning the code does not require internet, but the WhatsApp chat that opens needs the device to be online.
