How to create a reliable QR code
Choose suitable content, contrast, size and quiet space so people can scan your QR code reliably.
Practical steps
Open the QR Code Generator and choose the content type that matches what you want to share. Complete the required fields, keep a dark code on a light background, use at least four modules of quiet space, and choose Q or H error correction when adding a logo. Download the PNG and use the built-in image scanner to confirm that the decoded value matches before printing or sharing it.
Privacy and safety
Your selected files stay on your device. Keep backups, work only with files you are authorized to use, and verify every result.
