What can I encode in a QR code?

URLs, plain text, email addresses, phone numbers, Wi-Fi credentials, and more. Any text up to ~4000 characters can be encoded.

Can I customize the QR code colors?

Yes! Choose any foreground and background color. Make sure there's enough contrast for scanners to read it properly.

What size should I use?

300x300 works for most uses. Use 400x400 or 500x500 for print. 150x150 is fine for small digital displays.

Is the QR code free to use?

Absolutely! Generate unlimited QR codes for free. No watermarks, no sign-up required.

Will the QR code expire?

No. QR codes encode data directly — they never expire. As long as the URL or content is valid, the QR code works forever.
