Frequently Asked Questions
What is the maximum amount of data a QR code can hold?▼
A QR code can store up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data. However, more data means a denser QR code that's harder to scan. For best results, keep content under 300 characters.
Can I customize the colors of my QR code?▼
Yes, you can change foreground and background colors. However, always maintain high contrast — dark foreground on light background works best. Avoid light-on-light or dark-on-dark combinations. The foreground should always be darker than the background for reliable scanning.
Why can't some QR scanners read my generated QR code?▼
Common issues include: insufficient contrast between foreground and background colors, too small a size for the amount of data, insufficient margin (quiet zone) around the code, or inverted colors. Ensure at least a 4-module margin and good contrast for best compatibility.
