- High contrast between foreground and background improves scan reliability. Light background + dark foreground works best.
- Longer text makes the QR pattern more complex, which can reduce readability at small sizes.
FAQ
- Is there a limit to how much data a QR code can hold?
- QR codes can store up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes. However, more data means a denser pattern, so shorter URLs are recommended.
- Can I use the generated QR codes commercially?
- Yes. QR codes are an open standard, so there are no licensing restrictions on commercial use.
- Will the QR code still scan if I invert the colors?
- Some scanners can read inverted QR codes, but it is not guaranteed across all devices. Sticking with a dark foreground on a light background is the safest choice.
