Make a QR code for a link, text, email, phone or WiFi.
Fill in the details to see your QR code.
Three steps
A link, plain text, an email address, a phone number or WiFi credentials.
Type or paste the content. The code regenerates as you type.
PNG for the web and for slides, SVG for print at any size.
Why this one
A QR code on a poster or a menu needs to be vector, or it will be a blurry approximation of a machine-readable thing, which is worse than useless.
The WiFi format encodes the network name, password and security type in the exact structure phones expect, so scanning connects rather than showing a string.
The code encodes your URL directly. Many free generators point at their own domain first, which means their link dies and your printed code dies with it.
The short version
QR codes went from a punchline to infrastructure in about two years, and the main thing that separates a working one from a wasted print run is boring: enough physical size, enough contrast, and a URL encoded directly rather than routed through a service that can disappear. A printed code cannot be edited, which makes the second point matter far more than it seems at the time.
Questions
No. The URL is encoded directly into the pattern, so there is no intermediate service that can shut down. That is the difference between a static code and a "dynamic" one from a service that requires a subscription to keep working.
About two centimetres square for a short URL scanned from close range. Longer content needs a denser pattern and therefore more physical space. Test at actual size before printing a thousand of them.
SVG for anything printed, since it stays sharp at any size. PNG for screens, emails and slide decks where a raster is simpler to place.
Not with this tool. QR codes carry error correction that tolerates a small central cover, but the safe amount depends on the content length, and getting it wrong produces a code that scans on your phone and fails on someone else's.
