Best Practices for WhatsApp QR Codes That Get Scanned

A QR code only works if it scans the first time. Follow these tips before you print.

📏
Print it at least 2 × 2 cm. For signs, make the code about one tenth of the scanning distance. Scanned from 2 m away? Go for 20 cm.
◐
Keep strong contrast. Use a dark code on a light background. Light codes on dark backgrounds fail on some scanners.
⬜
Leave white space around it. The quiet border helps cameras find the code. Don’t crop it or place text over it.
↔️
Never stretch it. Always keep the QR code square. Use SVG when resizing for print so edges stay sharp.
📣
Tell people why to scan. A short call to action like “Scan to get a quote on WhatsApp” lifts scans noticeably.
✂️
Keep the message short. Longer messages make denser codes that are harder to scan when printed small.
🏷️
Use one code per placement. Give each poster, pack or event its own reference code in the message to compare results.
✅
Test before you print. Scan with both an Android phone and an iPhone, and confirm the right chat opens.

Using WhatsApp QR Codes and Links with the WhatsApp Business API

For numbers on the WhatsApp Business Platform, every scan or tap is a customer-initiated entry point for your team and automations.

When a customer taps send, a 24-hour customer service window opens, so your team or chatbot can reply with free-form messages without needing an approved template.

With Chakra Chat, the pre-filled message becomes a trigger: tag where the lead came from, route the chat to the right team, or start a WhatsApp chatbot flow. Estimate reply costs with the WhatsApp API pricing calculator.

📷
Customer scans or taps. WhatsApp opens with your number and message ready.
💬
They tap send. A 24-hour customer service window opens for free-form replies.
🏷️
Keyword tags the source. A code like STORE-01 or WEB-01 shows which placement worked, using source tracking.
🤖
Automation takes over. Chat triggers reply, qualify and assign the lead.

Frequently Asked Questions

Everything you need to know about WhatsApp QR codes and pre-filled messages

What is a WhatsApp QR code?
A WhatsApp QR code is a scannable code that opens a WhatsApp chat with your business number. When it includes a pre-filled message, the customer only has to tap send to start the conversation. Behind the code is a standard wa.me click to chat link.
Is this WhatsApp QR code generator really free?
Yes. You can create unlimited WhatsApp QR codes for free, without signing up. There is no watermark on PNG or SVG downloads and the codes do not expire.
Do WhatsApp QR codes expire?
No. The codes created here are static, so they keep working for as long as the phone number is active on WhatsApp.
Can I change the number or message after printing?
No. A static QR code stores the link itself, so changing the number or message means creating and printing a new code. If you expect changes, point the QR code to a page you control and update the WhatsApp link there.
Does this work with WhatsApp Business API numbers?
Yes. WhatsApp QR codes work with any number registered on WhatsApp, including numbers on the WhatsApp Business Platform (Cloud API), the WhatsApp Business App and personal WhatsApp accounts.
How can I track which QR code a lead came from?
Add a short, unique reference to the pre-filled message for each placement, for example Hi, I found you at the Pune expo (EXPO-PUNE). On a WhatsApp API platform like Chakra Chat, you can use that keyword to tag the contact, route the chat or start a chatbot automatically.
What size should I print my WhatsApp QR code?
Print it at least 2 cm by 2 cm (about 0.8 inches). For posters and signs, a good rule is that the QR code should be about one tenth of the scanning distance, so a code scanned from 2 meters away should be around 20 cm wide.
Which download format should I choose: PNG, SVG or PDF?
Use PNG for websites, social posts and presentations. Use SVG for print and design tools like Figma, Canva or Illustrator because it scales to any size without losing sharpness. Use PDF when you want a print-ready page to send straight to a printer.
Why is my WhatsApp QR code not scanning?
The most common causes are a code printed too small, low contrast between the code and background, a cropped white border or a stretched image. Also check that the number is registered on WhatsApp and includes the country code.
Is my phone number or message stored?
No. The QR code and link are created entirely in your browser. Your number and message are not sent to or saved on our servers.
