How to print QR Codes correctly?
If you are printing your QR code on physical material, follow these rules:
- Contrast is Key: Always use a dark foreground on a light background. Reverse colors (white on black) are often not scannable by older phones.
- Leave a Margin: Keep the "Quiet Zone" (white border) around the code. Our tool includes this by default.
- Test Size: For flyers, 2x2 cm is the minimum recommended size. For billboards, scale it up significantly.
- Use Vector/HD: Always download the largest size available (1000px) to avoid pixelation on print.
Static vs Dynamic QR Codes
This tool generates Static QR Codes. This means the data is embedded directly into the image.
Pros: Unlimited scans, never expires, 100% free, works offline.
Cons: You cannot change the link after printing. If you need to change the URL later, you must reprint the code.
