QR Code Link Checker
Extract the URL behind a QR code locally in your browser, review the destination, and scan only the link you choose before opening it.
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.

Always available if your browser cannot decode the image or the QR screenshot is too small or blurry.
QR destination

QR code link checker FAQ
How do I check the link behind a QR code?
Upload a clear QR image. CheckLink decodes it locally, shows the extracted destination, and lets you choose whether to scan that URL.
Does CheckLink upload my QR image?
No. QR image extraction happens locally in your browser using native QR detection when available or a local fallback decoder.
Can a QR code hide a phishing link?
Yes. A QR code can conceal a fake login page, lookalike domain, payment request, or shortened URL until it is decoded.
What if my browser cannot read the QR code?
Try a clearer image or paste the destination URL manually if your phone or app can preview it without opening it.
Does a low-risk result guarantee the QR destination is safe?
No. The result provides visible URL risk signals and context, not a guarantee.
