Do QR codes generated here expire?

No. A QR code is just a static image of the data you entered — there is no server, no link shortener and no expiry. It will scan forever as long as the underlying text is valid.

What is error correction and which level should I pick?

Error correction (L/M/Q/H) lets a damaged or partially obscured QR still scan. Higher levels add redundancy but make the code denser. Pick H if the code will be printed on packaging; M is fine for screens.

Can I generate a QR code that opens a website?

Yes — paste a full URL including https:// and most phones will offer to open it when scanned. URLs without a scheme may be treated as plain text.

Is there a limit to the amount of text I can encode?

Technically up to ~2,953 bytes, but QR codes get denser and harder to scan as the input grows. For long text, consider a URL shortener first.

Are my QR codes uploaded to a server?

No. The QR is rendered locally with the qrcode library. Open DevTools → Network and you'll see zero outbound requests.

Can I use these QR codes commercially?

Yes. There are no watermarks, no attribution required, and the underlying QR standard is royalty-free.
