A QR code you make here never expires. It is static: your content is encoded directly into the black-and-white pattern, generated in your browser, with nothing sent to a server and nothing to renew. There is no subscription that can lapse and no redirect service that can be switched off.
A QR code is a grid of squares that represents data using the same kind of error-corrected encoding used by barcodes, just in two dimensions instead of one. When you type a URL, a WiFi password, or a phone number into the generator, that exact text is converted into the grid pattern you see. A scanner reads the pattern back into the original text and acts on it, the same way it would if you had typed that text yourself. The pattern is drawn in your browser, and once you download the image the file stands on its own: nothing in it refers back to this site, so there is nothing that can be switched off later. That holds for every static type the generator makes: a URL, WiFi credentials, a vCard contact card, an email, a phone number, an SMS or a calendar event.
Some QR code generators, especially ones built around scan tracking, do not encode your real destination at all. Instead they encode a short link on a domain the provider controls, and that link redirects to your actual content. This is called a dynamic QR code, and it is genuinely useful: the provider can log every scan and let you change the destination without reprinting anything. The trade-off is that the code now depends on that provider's redirect staying online. If the free plan expires, the account is deleted, or the company shuts the service down, the code still scans, but it opens nothing, because the middleman it pointed to is gone. That is not a flaw in QR codes as a technology; it is a property of the business model layered on top of them.
The trade is real in the other direction too. A static code cannot be edited after you print it: if the URL changes, you need a new code. It also cannot tell you how many times it was scanned, where, or on what device, because nothing calls home. That trade is worth making for anything permanent or one-off: a business card, a WiFi network sign, a plaque, a warranty label, a menu that rarely changes. It is the wrong trade for a time-limited campaign where you need to swap the destination mid-run or want scan counts as a marketing metric. For that, a dynamic code with analytics from a provider you trust to stay in business is the better fit. There is also a middle path: point a static code at a short address on a domain you control and redirect from there. The printed code stays valid, and you change the redirect yourself when the destination moves. See how to change a QR code's destination without a subscription for the setup, including why that redirect should be a 302 rather than a 301.
The content you enter is turned into an image in your browser. Nothing you type is uploaded or stored. The only measurement this site makes is ordinary page-view analytics, the same as any website, not scans of the codes you make.
No. A static QR code generated here encodes your content directly into the image itself, so once you download it, it has no ongoing connection to Quick QR Maker. It will keep working for as long as the thing it points to (a website, a WiFi network, a phone number) still exists, regardless of whether this site is online.
A static QR code does not expire on its own; it is a fixed pattern of black and white squares, and scanning it always decodes the same data. What people usually mean by "my QR code expired" is that it was a dynamic code whose provider stopped redirecting it, which is a business decision, not a property of the QR code standard.
A static code stores your actual content (a URL, WiFi credentials, a phone number) inside the QR pattern. A dynamic code stores a short redirect link owned by a provider, which then forwards the scanner to your real destination. Static codes cannot expire; dynamic codes stop working the moment the provider stops running that redirect.
No. The QR code image is drawn in your browser, and the content you type never leaves your device. There is no record anywhere of what a code made here contains.
You cannot change the destination after printing, and you cannot see how many times it was scanned. If a link changes or you need scan counts for a campaign, you need a dynamic code and a provider willing to keep that redirect running indefinitely.
No. There is no sign up and no login. Enter your content and download the image.
