Expert Guide: Pro-Tips for Scannability (Experience)

Our experience shows that two common mistakes break QR codes. First, **low contrast**. Always use a dark foreground and a light background. Never use inverted colors (like white on black) as some scanning apps can't read them. Second, **test your code** with multiple apps (both iPhone and Android cameras) before printing.

What is Error Correction? (Expertise)

Error correction allows a QR code to be scanned even if part of it is damaged or covered. This QR Code Generator offers four levels, but there is a trade-off. A "High" (H) level is more reliable but creates a more dense, complex code that can be harder to scan at very small sizes. For most users, "Medium" (M) is the perfect balance of reliability and simplicity.

• Medium (M): (Default) Can withstand up to 15% damage. Excellent for most use cases.
• High (H): Can withstand up to 30% damage. Use this *only* if you plan to place a large logo in the center of your code.
