The error correction level determines how much of the QR code can be damaged or covered while still remaining readable. L can recover about 7%, M about 15%, Q about 25%, and H about 30%. Higher levels make the QR code more complex but more resilient.
A logo covers some modules in the center of the QR code, but error correction allows most codes to scan normally. When adding a logo, use error correction level Q or H and keep the logo size at 20% or less.
No. QR code generation is processed 100% in your web browser. Text, URLs, phone numbers, and other input data are never sent outside your device.
QR code versions range from 1 to 40. Higher versions can store more data. Version 1 has 21 x 21 modules, and each version increase adds 4 modules per side. If you choose Auto, the smallest suitable version is selected automatically for your input.
Use it when you need to turn a URL, contact detail, email, phone number, or short message into a QR code image.
