FAQ
What are error correction levels?
QR codes include redundancy data. Higher levels let scanners read the code even if parts are damaged. Low = 7%, Medium = 15%, Quartile = 25%, High = 30% recovery.
Why does color contrast matter?
Scanners rely on high contrast between foreground and background. Use a dark foreground on a light background. Low-contrast pairings may fail to scan.
Can I encode email or WiFi data?
Yes. Use the tabs above to switch between Link, Text, Email, Wi-Fi, and Contact card formats. Each generates the correct schema for scanners.
