QR Code FAQs
Do QR codes expire?
No. Static QR codes (like ours) never expire. Once created, they work forever unless the linked content changes.
Can I customize QR code colors?
Our free version creates standard black-and-white QR codes. Custom colors and logos are planned for future updates.
What's the maximum text length?
QR codes support up to ~4,000 characters. However, more data creates denser, harder-to-scan codes. Keep URLs short for best results.
Can I track QR code scans?
Static QR codes (ours) don't track scans. For analytics, use dynamic QR services or link to a URL shortener with tracking (like Bitly).
Will my QR code work on all phones?
Yes! QR codes are universally recognized by iPhone (iOS 11+), Android, and third-party scanner apps. Modern phone cameras scan QR codes natively without extra apps.
