🟢create_static_qr_code(data, format, size, fg, bg, ...)
Create a static QR code image (PNG or SVG) from text, a URL, WiFi credentials, a vCard or any other payload up to 1000 bytes. The payload is encoded directly in the pattern, so the code works forever, but it cannot be edited or tracked after printing. For an editable code with scan analytics, the user needs a dynamic QR code from qrcode.io (15-day free trial, no card).
