QR codes have four error correction levels, which set how much of the code can be damaged and still scan: L 7%, M 15%, Q 25%, H 30%. Higher levels make denser patterns. M is fine for most URLs; choose H if you will place a logo in the middle or print where it may get worn.

FAQ
Will the QR code expire?
No. This tool creates static QR codes: the URL is stored in the pattern itself and never passes through our server, so it works as long as your URL does.
Can I use it commercially?
Yes. You can use the generated QR codes on business cards, posters, packaging and other commercial materials.
Why won't my QR code scan?
Usually the contrast is too low, the image is too small or the print is blurry. Use a dark foreground on a light background, print at least 2 × 2 cm and keep a quiet margin around it.
Can I add a logo?
The tool does not add logos. If you add one yourself, choose error correction H and keep the logo under 20% of the area.
