Do the generated QR codes ever expire?

No. All QR codes generated are static, standard QR codes that store the data directly in the pattern. They will never expire and require no external redirection.

Can I create a WiFi QR code for guests?

Yes. Choose the "WiFi" type, enter your network name (SSID) and password. When guests scan it with their camera, their device will connect automatically.

What formats can I download the QR code in?

You can download high-resolution raster PNG images (up to 2048x2048 for print) and crisp scalable vector SVG graphics.

Can I use these QR codes for commercial products and marketing?

Yes, 100%! All QR codes generated on LutaTech are free to use for both personal and commercial purposes, including product packaging, restaurant menus, billboards, websites, and business cards.

How does the WiFi QR code work?

When a guest scans a WiFi QR code using their iPhone or Android camera, the phone automatically recognizes the network name (SSID) and security password, prompting the user to connect without manually typing the password.

Which error correction level should I choose?

Level M (15%) is ideal for most digital and print uses. If you plan to print the QR code on merchandise, outdoor billboards, or curved surfaces where dirt or wear might occur, choose Level H (30%) for maximum resilience.
