Scan a QR code again before printing

A QR code needs a clear border around it. Cropping tightly or placing other graphics against the code can make detection harder. Keep the quiet space around the generated PNG.

Higher error correction can tolerate some damage but may require a denser grid for the same content. When printing small, use a short URL and test the actual printed result.

Upload the downloaded image to a QR scanner to confirm its contents. The tool does not verify URL ownership or the destination website. Review the address before printing.
