Tips for better results
- For print work, SVG is the safest choice because it stays sharp at any physical size.
- Keep strong contrast between the QR color and background.
- Longer content produces a denser QR code, so use the recommended minimum print-size indicator.
- A center logo is automatically limited to about 18% of the QR width and receives a white safety area.
Frequently asked questions
How are pixels and millimeters linked?
Zavilo converts between pixels and millimeters using the selected DPI. Changing either value updates the other automatically.
What size should I use for printing?
The generator calculates a recommended minimum size from the QR module count. Larger or denser QR codes generally need more physical space.
Can I add my logo in the center?
Yes. Choose a logo image and it is automatically centered and scaled to a conservative size. High error correction is enabled while a logo is used.
Should I download PNG or SVG?
PNG is convenient for screens and documents. SVG is recommended for professional printing because it scales without losing edge sharpness.
