QR Code Generator FAQ
Quick answers, no fluff.
Back to the generator →What size should a QR code be?
Big enough to scan comfortably at the viewing distance. For print, SVG is ideal because it scales perfectly.
Should I use a transparent background?
Only if the placement background is high-contrast. For maximum reliability, use a light background behind dark modules.
SVG vs PNG: which should I choose?
Choose SVG for print and scaling. Choose PNG if you need a raster image for a specific workflow.
Do QR codes expire?
The QR image doesn’t expire, but the destination can. If you use a short URL, your QR depends on that service staying up.
