A QR code (Quick Response code) is a two-dimensional barcode that can store various types of data like URLs, text, contact information, WiFi credentials, etc. Users can scan QR codes with smartphones to quickly access the encoded information without typing.

How do I create a QR code for my website?

To create a URL QR code: 1) Select "URL" type, 2) Enter your website URL (e.g., https://example.com), 3) Click Generate, 4) Download the QR code as PNG or SVG. The QR code will redirect users to your website when scanned.

What error correction level should I use?

Error correction allows QR codes to be readable even if partially damaged. Levels: L (7% recovery, smallest), M (15%, recommended), Q (25%), H (30%, most durable). Use M for general purposes, H for printed materials that may get damaged, and L for digital-only QR codes to minimize size.

No, QR codes generated by this tool never expire. The data is embedded directly in the QR code image itself, not stored on a server. As long as you have the QR code image, it will work forever. This is true for all static QR codes (URL, text, contact, etc.).

Can I create WiFi QR codes?

Yes! Select "WiFi" type and enter your network name (SSID), password, and security type (WPA/WEP/None). When users scan the QR code, their device will automatically prompt to connect to your WiFi network without manual password entry. Perfect for guest WiFi access.
