Can I add a logo in the center of the QR code?

Yes. Use "Add logo" to upload an image (e.g. your brand logo). Choose error correction H (30%) so the code still scans reliably with the logo in the center.

Can I create QR codes for WiFi passwords?

Yes. Enter your WiFi credentials in the standard WiFi QR format and the tool will generate a scannable code.

What sizes are available?

You can generate QR codes from 128×128 to 512×512 pixels. Logo size is adjustable as a percentage of the QR size.

Do the QR codes expire?

No. QR codes are just encoded data — they don't expire. As long as the URL or data is valid, the code works.

What are QR codes best used for?

Sharing URLs (menus, landing pages, WiFi), contact info (vCards), payments, event check-in, or any short text. Keep the payload short for better scan reliability.
