ⓘ Option guide / important notes

QR option guide

QR size controls the downloaded PNG resolution, not the on-screen preview size. The preview remains a fixed display size.
Error correction is approximately L 7%, M 15%, Q 25%, H 30%. M suits ordinary on-screen QR codes, M/Q for print, and H is recommended when adding a logo.
These percentages do not mean any matching portion of the QR can be covered and still scan. Real recognition depends on data density, size, logo, print quality, contrast, quiet zone and camera conditions.
Higher error correction can make the same payload denser, so H is not always the best choice.
Margin is the quiet zone around a QR code. Too little margin can reduce recognition on some scanners.
Use a dark foreground on a light background. Transparent backgrounds still need strong contrast against the final surface.
Use H with a logo and keep the logo small. A successful self-check does not guarantee every phone or printed copy will scan, so test the downloaded result on a real device.
