9 Ways to Fix WhatsApp Web No Valid QR Code Detected

Are you trying to scan the QR code on WhatsApp but continuously getting a “No Valid QR Code Detected” or an “Invalid QR code” error? If so, you are not alone on the internet, as many users have reported the same issue on Reddit and other social sites. Today, you will learn how to fix the WhatsApp Web No Valid QR Code Detected issue.

WhatsApp Web lets users send and receive messages from their computers or other device with browser support. Once you connect your phone by scanning a QR code visible on the computer from your mobile device, it will sync all the WhatsApp messages to the web version.

While the WhatsApp Web links smoothly all the time, sometimes it starts giving errors like can’t scan QR code and others. Read on to check out the troubleshooting ways to fix the No Valid QR Detected issue.

Zoom In The Web Page

The first thing you need to do is zoom in on the WhatsApp Web page on the browser to 125% or above, as your mobile phone might not be able to detect the QR code due to its size.

To zoom in on the web page, click the ‘Ctrl’ and ‘+’ keys at once for Windows computers or the ‘Command’ and ‘+’ keys at once for Mac computers. Once you do, the QR code will increase and can be easily scanned using the phone.

Check Your Internet

If zooming in on the WhatsApp Web page does not help you resolve the problem, then you need to check whether you are getting good and stable internet speed on your computer and mobile device.

Visit a speed checker website, like fast.com, speedtest.org, etc., to check your internet speed, and if you are receiving slow speed, switch to a stable connection, and your issue should be fixed.

Note that QR codes for WhatsApp Web expire within a few seconds due to security, so scan the new code after reloading the page.

Use the Linked Devices Option to Scan the QR Code

If you are using the WhatsApp camera to scan the QR code, then you will not be able to scan it as WhatsApp has a QR code scanner under the Linked Devices option, which is made for linking your account to other devices, including WhatsApp Web, and this is the correct way to scan the QR code. Here’s how you can do it:

Step 1: Open the WhatsApp app and navigate to Settings then choose Linked Devices. For Android phones, tap on the three-dot icon at the top and select Linked Devices.
