About This Tool
QR codes were invented in 1994 by Denso Wave for tracking automotive parts, but they exploded into mainstream use after smartphone cameras gained native QR scanning in 2017. Today they appear on menus, business cards, product packaging, event tickets, billboards, and payment systems.
Our QR code generator uses the standard ISO/IEC 18004 QR code specification. Each code includes error-correction data (level M by default), meaning the code can still be scanned even if up to 15% of it is damaged or obscured. Higher error-correction levels make the code more robust but also more complex (denser pattern).
Useful for: sharing a website URL on a printed flyer; restaurant menus using QR codes instead of physical menus; sharing Wi-Fi passwords without typing; linking a physical product to its online listing; event check-in systems; contact cards (vCard QR codes).
Frequently Asked Questions
Do the QR codes expire?
No. Our tool generates static QR codes that store the data directly in the pattern. They work forever and require no account or subscription to maintain.
What can I encode in a QR code?
URLs, plain text, email addresses (mailto:), phone numbers (tel:), SMS messages, Wi-Fi credentials (SSID + password), and vCard contact information.
What's the minimum print size for a QR code?
For reliable scanning, print QR codes at least 2 cm × 2 cm (approx. 0.8 inches) with a quiet zone (white border) around all four sides.
Can I customize the color of the QR code?
Standard QR codes use black on white. For best scan reliability, maintain maximum contrast between foreground and background colors.
Is the generated QR code free to use commercially?
Yes. QR codes are an open standard. You can use codes you generate here on products, marketing materials, and commercial projects without restriction.
