Resolution refers to the clarity and detail of a QR code image, measured in DPI (dots per inch) for raster formats or as vector for SVG.
Raster formats (PNG, JPEG) have a fixed pixel grid. At low resolution, individual modules become blurry and unscannable. Vector formats (SVG) use mathematical shapes and scale infinitely without quality loss. For print, always use 300 DPI minimum or SVG.
Export at 300+ DPI in PNG or use SVG for perfect print quality at any size.
72-150 DPI is sufficient for screens.
SVG is ideal — scales from business card to billboard.
300 DPI minimum. For large format printing, use SVG to avoid pixelation.
PNG is a raster format with fixed pixels. SVG is a vector format that scales infinitely without quality loss.
Upscaling adds blur. Regenerate the QR code at the correct resolution instead.
