Frequently Asked Questions (FAQ)
Is my uploaded image uploaded to a server?
No. The QR Code Reader runs completely inside your browser using canvas pixel buffer sniffing. Your uploaded images and decoded data never leave your computer.
Why does it say could not decode QR code?
Make sure the QR code in the image is not blurred, cut off, too low in contrast, or excessively distorted. For best results, use a clear, flat photo under good lighting.
