Who controls this QR code?
Upload a picture of a QR code, scan it with your camera, or paste the link inside it. We show who decides where it sends people. Checked in your browser: nothing you upload, scan or paste leaves this page unless you press Check redirects, which sends only that link to Qrzo.
Other results you might see
Your own domain
Only whoever controls the domain can change it.
qrzo.app
Protected by the Redirect Promise. Can’t be switched off for non-payment.
Static code
The link is in the pattern, so no QR vendor can edit or switch it off. The site it points to can still change or go away.

Samples are example links, not live codes.
Why the first link decides
A dynamic QR code holds a short link. Every scan asks that short link's owner where to go, and they can change the answer at any time. Later hops only happen because the first one says so. So the company behind the first domain controls the code, whoever printed it.
We read the link in your browser. If its domain is not a vendor we know, we say we could not confirm who controls it: it may be the site itself, or a vendor serving short links from that domain.
We follow the link only if you press Check redirects. Your browser then sends that one link to Qrzo's server, which follows up to 5 redirects without opening any page and shows each hop, the final destination and its status. We do not store or log the link or the result. To keep the check free, each connection gets 10 checks a minute and 50 a day; past that, or if the check is down, you still see the verdict from the link alone. Qrzo links are not followed, because that would count as a scan.
Qrzo codes
A qrzo.app code is controlled by its account owner, not by Qrzo's billing. Our redirect never reads plan or payment state, so a code keeps going to its last saved destination after a trial ends or you cancel. Free codes are locked at creation: they redirect forever to the destination set when they were made, and cannot be edited. Read the Redirect Promise.
