A QR code (Quick Response code) is a two-dimensional barcode that stores information in a matrix of black and white squares. When scanned by a smartphone camera or QR scanner app, the encoded data—such as URLs, text, phone numbers, or WiFi credentials—is instantly decoded and made accessible to the user.

Yes! Our QR code generator is completely free. There are no hidden fees, no registration required, and no watermarks on your downloaded QR codes. Generate unlimited QR codes for personal or commercial use without any restrictions.

Absolutely. You can upload your brand logo (PNG, JPG, or SVG) and it will be placed in the center of the QR code. We recommend using the "High" error correction level when adding a logo to ensure the QR code remains scannable even with the logo overlay.

Our generator supports 7 data types: URL (website links), Text (any plain text), Phone (direct dial), SMS (pre-filled messages), Email (with subject and body), WiFi (network credentials for easy sharing), and vCard (digital business cards with contact information).

Static QR codes (like the ones generated here) do not expire. The data is encoded directly into the QR pattern, so as long as the content (URL, text, etc.) remains valid, the QR code will continue to work indefinitely. Dynamic QR codes from other services may expire when subscriptions end, but our static codes are permanent.

Error correction allows a QR code to be scanned correctly even if part of it is damaged, dirty, or covered (e.g., by a logo). Levels range from L (7% recovery) to H (30% recovery). We recommend using Level H for QR codes with logos and Level M or Q for standard use.

Yes! You can freely customize both the foreground (dark squares) and background colors. Choose from our preset color palettes or use the color picker for exact brand colors. For best results, maintain strong contrast between foreground and background to ensure reliable scanning.
