QR codes have become a ubiquitous tool for accessing information quickly and efficiently. However, there are times when you may encounter a QR code on your desktop or laptop computer screen or on a phone that you are currently using, leaving you without the option to scan it with a camera. This situation is more common than you might think.
For instance, you could be working on a PC without a connected camera, or you might want to scan a QR code that’s displayed on your own smartphone, which you can’t photograph with the device’s camera. In such scenarios, the challenge is to find a way to read the QR code without the traditional method of pointing a camera at it.
In this article, we will explore a practical solution to this problem: using web-based tools like webqr and Google Lens. These tools allow you to scan QR codes directly from your screen without needing a separate device with a camera. The process is straightforward and effective, providing a convenient alternative for those moments when a camera isn’t available or practical.

Scanning a QR code without a camera using online tools
When you need to scan a QR code displayed on your computer screen or on the same smartphone you are using, the typical method of using a camera is not feasible. Fortunately, there are online tools like WebQR.com that offer a solution. Here’s a step-by-step guide to using WebQR.com for scanning a QR code without a camera:

- You can upload the QR code image in two ways: either by dragging the image directly onto the website or by clicking on the “Select file” option. If you choose “Select file”, navigate to the folder where you have saved the QR code image and select it.
- After selecting the file, WebQR will scan the QR code and display its content on the screen.
This method is particularly useful when the QR code is already in a digital format, such as an image file on your computer or a display on your smartphone screen.
