Frequently Asked Questions (FAQs)
No. The QR codes generated on our website are static, meaning they embed the actual text or URL content directly. They do not rely on redirection links, meaning they will function indefinitely and never expire.
For physical materials (business cards, brochures, posters), the minimum size should be at least 2cm x 2cm (0.8 x 0.8 inches). Using our vector SVG download option ensures the QR code remains crisp at any print scale.
QR scanners require high contrast to parse the matrix. If the foreground and background colors are too similar, or if you reverse the colors (e.g. light foreground on dark background), scanners may fail. Always verify with your mobile camera.
