Upload QR image

Your QR image stays in your browser. CheckLink only receives the extracted URL if you choose to scan it.

Native browser QR detection is unavailable, so CheckLink is using a local fallback decoder.

FAQ

Does CheckLink upload my QR image?

No. QR image extraction happens locally in your browser using native QR detection when available, or a local browser fallback decoder.

Why can QR codes be risky?

QR codes hide the destination, so users may open payment, login, or download links without reading the URL first.

What if my browser cannot read the QR?

Try a clearer image or paste the QR destination URL manually if your phone or app can preview it.

Is a low-risk result a guarantee?

No. It is a risk signal based on available information, not a guarantee.
