QR Code File Formats Explained
Definition: QR code file formats determine the image quality, scalability, and compatibility of generated QR codes for different use cases like print, web, and merchandise.
Choosing the right file format for your QR code depends on where it will be used. PNG is best for digital use (websites, emails, social media) at specific resolutions. SVG is ideal for print because it scales infinitely without quality loss. PDF works for professional print workflows. EPS is needed for some legacy design software. For large-format printing (billboards, banners), SVG or high-resolution PNG (300+ DPI) is essential.
Key points
- PNG: best for web and digital use
- SVG: infinite scaling for any print size
- PDF: professional print workflows
- EPS: legacy design software compatibility
- 300 DPI minimum for print quality
- SVG preferred for large-format printing
Frequently asked questions
What format should I use for printing QR codes?
SVG for the best quality at any size. If your print workflow requires raster images, use PNG at 300 DPI minimum.
What format for websites and email?
PNG at 200-400px is ideal for web. SVG also works on modern browsers and renders crisply on retina screens.
Can I convert between QR code formats?
Yes — it's best to convert from vector (SVG/PDF) to raster (PNG). Converting raster to vector may lose quality.
