Frequently Asked Questions

Does this upload my QR code image to a server?

No. The image is decoded entirely in your browser using JavaScript. Nothing is uploaded or transmitted. You can even disconnect from the internet after the page loads and it will still work.

Why can't my QR code be detected?

Common causes: the image is too low resolution, the QR code is partially obscured, or the contrast is poor. Try using a higher-quality screenshot. The decoder works best on images where the QR code fills most of the frame.

What types of QR codes can this decode?

Any standard QR code URLs, plain text, vCards, Wi-Fi credentials, otpauth:// URIs, and more. It does not support proprietary formats like Aztec codes or DataMatrix.
