Frequently Asked Questions
What data can I put in a QR code?▼
QR codes can encode URLs, plain text, email addresses, phone numbers, WiFi credentials, vCard contacts, and more. URLs are the most common use case. The maximum data capacity depends on the error correction level and data type.
What is QR code error correction?▼
Error correction allows a QR code to be scanned even if part of it is damaged or obscured. There are four levels: L (7%), M (15%), Q (25%), and H (30%). Higher correction means the QR code can tolerate more damage but requires a denser pattern.
What size should a QR code be for printing?▼
A QR code should be at least 2cm x 2cm (0.8in x 0.8in) for close-range scanning. For posters or billboards, use the rule of thumb: the QR code should be 1/10th of the scanning distance (e.g., 10cm for 1 meter distance).
Can QR codes expire?▼
Static QR codes (like those generated by this tool) never expire because the data is encoded directly in the image. Dynamic QR codes (which redirect through a service) can expire if the service is discontinued or the subscription lapses.
