Is the QR code generator completely free?

Yes — fully free, no account needed, no watermarks, no limits.

Are my QR codes stored anywhere?

No. Everything runs in your browser. The History tab stores codes in your device's localStorage only — nothing is sent to any server.

What error correction level should I use?

M (15%) works for most uses. Use H (30%) if you want to add a logo in the center — higher error correction means the code stays scannable even when part of it is covered.

Can I add a logo to the QR code?

Set the error correction to H, generate the QR at 1024px or higher, download as PNG, then overlay your logo using an image editor. The H level ensures the code remains scannable.

What is the maximum data a QR code can hold?

QR codes can hold up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data. Using more data requires more modules (denser code) and a larger physical print size.

What formats can I download?

PNG (lossless, best for most uses), JPEG (smaller file), WebP (modern web format), and SVG (vector, infinitely scalable for print).
