What is error correction level and which should I use?

Error correction lets QR codes be read even when partially damaged or obscured. Use L for clean digital screens, H for printed materials that may wear. M is a good default for most uses.

What is the maximum data a QR code can hold?

A QR code can hold up to 3KB of data — roughly 7,000 numeric or 4,000 alphanumeric characters. Shorter URLs produce simpler, faster-scanning codes.

Can I add a logo to the center of the QR code?

Yes, using the Logo option. Keep the logo under 25% of the QR code area and set error correction to H so the code remains fully scannable despite the covered modules.
