Generate QR codes with custom colors, sizes, and error correction levels.

25×25 modules · ECC M

Generated client-side with qrcode-generator (MIT): nothing is uploaded. Error correction trades size for damage resistance, L being the smallest and H the most resilient. WiFi codes use the WIFI:T:WPA;S:SSID;P:password;; format, and vCard encodes full contact details for phone scanners.

Frequently Asked Questions

M (15%) is a good default. Use H for codes printed on labels or surfaces likely to be damaged, L for clean digital screens where capacity matters.

Yes, use the WiFi preset which generates the WIFI:T:WPA;S:...;P:...;; format supported by most phone cameras.
