FAQ

What size should I use?

300×300 works for most uses (screens, documents). Use 400+ for print materials. The QR code is vector-based internally, so larger sizes stay crisp.

Can I customize colors?

Yes! Use the foreground and background color pickers. Ensure high contrast for reliable scanning — dark foreground on light background works best.

Do QR codes expire?

No. QR codes generated here are static — they encode the data directly. They will work forever as long as the encoded URL or resource is still available.
