How to use
Error correction levels
QR codes have built-in error correction so they still scan when partially damaged. L: tolerates ~7% damage — use for clean digital QR codes. M: 15% — good default. Q: 25% — for printed materials likely to get scratched. H: 30% — required when adding a logo in the centre, as the logo "damages" part of the code.
What you can encode
QR codes hold URLs, phone numbers (tel:), email (mailto:), text messages (SMSTO:), Wi-Fi credentials (WIFI:), business cards (BEGIN:VCARD), and plain text. Most QR readers automatically recognise common formats. Keep URLs short — long URLs make denser, harder-to-scan codes.
Frequently asked questions
What can I put in a batch of QR codes?
Any list of URLs or text, one entry per line. Each line becomes its own QR code that you can download as a PNG.
How large should a printed QR code be?
As a rule of thumb, at least 2 cm by 2 cm for close scanning, larger if it will be viewed from a distance. Leave a clear margin around the code and test it with a phone before printing.
Do the QR codes expire?
Codes generated here encode your data directly, so they do not expire. A code pointing to a URL works for as long as that URL does.
