How the QR scanner works

Upload any image file containing a QR code and the scanner will decode it instantly in your browser. The image processing happens entirely on your device. Nothing is uploaded to any external server. You can also use your device camera to scan QR codes in real time.

The scanner works on screenshots, photos, PDF exports, or any image file that contains a clearly visible QR code. For best results, make sure the QR code is not blurry or partially cropped out of frame.

Frequently asked questions

What image formats does the scanner support?
The scanner accepts PNG, JPG, GIF and WebP image files. Most screenshots and photos taken on a smartphone will work. Make sure the QR code is in focus and fully visible in the image for reliable decoding.
Is my image uploaded to a server?
No. The image is read and processed entirely in your browser using JavaScript. It is never uploaded to any server, stored anywhere or transmitted over the network. Your file stays on your device the entire time.
Why did the scanner not find a QR code in my image?
Common reasons include the image being blurry or low resolution, the QR code being partially cut off, the contrast between the code and background being too low, or the image containing a damaged or incomplete QR code. Try a clearer, higher resolution image and make sure the entire code is visible.
