QR (Quick Response) code is a 2D barcode that can store text, URLs, contact info, and more. It can be scanned by smartphones and dedicated readers.

What is error correction level?

Error correction allows QR codes to be read even if partially damaged. L=7%, M=15%, Q=25%, H=30% of the code can be damaged and still work.

How much data can a QR code hold?

Maximum capacity depends on error correction: up to 4,296 alphanumeric characters (L), 2,953 (M), 2,331 (Q), or 1,817 (H).

Can I add a logo to my QR code?

Yes, but use high error correction (Q or H) to ensure the code remains scannable. The logo should cover no more than 30% of the code.

What colors work best for QR codes?

Dark foreground on light background works best. Ensure high contrast. Avoid light colors on light backgrounds or inverted colors.

What size should my QR code be?

For print, minimum 2cm x 2cm. For scanning from distance, larger is better. The quiet zone (margin) around the code is important.

Static QR codes (like this tool generates) never expire. Dynamic QR codes (from some services) may expire based on the service.

What formats can I download?

You can download as PNG (raster image) or SVG (vector, scalable). SVG is better for print as it scales without quality loss.

Is my data stored anywhere?

No! QR codes are generated entirely in your browser. Your data never leaves your device.

Why is my QR code not scanning?

Common issues: low contrast colors, too small size, damaged/distorted code, or too much data. Try increasing size or error correction.
