Frequently Asked Questions
Q: Which image formats can I export the QR code to?
You can download the QR code as a high-resolution PNG image (ideal for general use and sharing) or as an SVG vector file (best for professional print or scalable web designs).
Q: What does the Error Correction Level (ECC) setting do?
Error correction allows the QR code to remain readable even if it is dirty, partially covered, or damaged. Low (7%) creates a simpler pattern, while High (30%) creates a denser pattern that can withstand significant damage or overlaying logos.
