Which error-correction level should I pick?

Level M (medium) is a good default. Use H (high) for codes that will be printed and may be partially damaged.

No — the code is generated locally. Whether a scan is tracked depends on the destination URL you encode.

Which error-correction level should I choose?

Low or medium is fine for screens and clean digital use. Choose high for print, especially on surfaces that may be scratched, curved or partially obscured — the code stays scannable with a portion damaged.

Do the codes expire or get tracked?

No. A QR code is a static encoding of the text you typed. There is no redirect service in between, no scan counter and no expiry — which also means you cannot change the destination after printing.

How small can I print a QR code?

As a rule of thumb keep it at least 2 x 2 cm for a short URL, and larger for longer content or greater scanning distance. Always test-scan the actual printed piece before ordering a run.

// What is the QR Code Generator?

The QR Code Generator turns any text, URL, phone number or Wi-Fi credential into a scannable QR code rendered directly in your browser as a plain black-and-white image. Contrast is what makes a code scan reliably in poor light or at an angle, so the output deliberately stays monochrome. You can adjust size and error-correction level: higher correction adds redundancy so the code still scans when part of it is scratched, covered or printed poorly — worth it for anything going onto physical media. The image is produced on a canvas in your tab and downloaded straight from memory, meaning the URL you encode is never sent to a server or logged anywhere.
