Tools
QR code scanner
Read a QR code from a screenshot, photo or your camera and check where a link goes before you open it. Images are never uploaded.
QR code size calculator
Find the smallest size to print a code for its scanning distance and content, with the module size and quiet zone.
Free QR code generators
Make a static QR code for a link, WiFi, a contact card, a menu and more. No sign-up, no watermark, never expires.
How these tools work
Both tools run on your device. The scanner decodes images with a decoder that runs inside your browser tab, so your image is never uploaded, and it shows what a code contains without opening anything. The size calculator does its arithmetic on the page, using the same rules as our QR code size guide.
Like the free QR code generators, they need no account. CirculateQR’s plans cover what runs on its servers, such as dynamic codes you can edit after printing, hosted pages and scan analytics; see pricing.
