Frequently Asked Questions
How much text can a QR code hold?
A QR code can store up to 4,296 alphanumeric characters or 7,089 numeric characters at maximum capacity. In practice, shorter content creates simpler, faster-scanning QR codes. For URLs, use a URL shortener if your link is very long.
Can QR codes be customized with colors or logos?
Basic QR codes use black and white for maximum scanability. While custom colors and logos are possible with specialized tools, they risk reducing scan reliability. Always test any customized QR code with multiple devices before printing at scale.
Do QR codes expire?
Static QR codes (like those generated here) never expire. They encode fixed content permanently. Dynamic QR codes, generated by third-party platforms, can expire if the service discontinues or if the redirect URL is removed.
What size should a QR code be for printing?
The minimum printable QR code size is about 2 × 2 cm (0.8 × 0.8 inches) for scanning at 30cm distance. For flyers and posters, use 4 × 4 cm or larger. The larger the print, the greater the scan distance. Download the largest size available for best print quality.
Can QR codes encode WiFi credentials?
Yes. The WiFi QR format is: WIFI:S:[SSID];T:[WPA/WEP/nopass];P:[password];; — many QR code readers and Android/iOS cameras can read this format to automatically join a WiFi network. Enter your WiFi details in this format to generate a shareable WiFi QR code.
