Choosing the wrong export format for your QR code can ruin an entire print run. If you send a low-resolution raster image (such as a 72 DPI JPG or PNG) to a commercial printer, the module edges will blur, rendering the code unscannable by smartphone cameras.
In this guide, we compare SVG, PNG, and PDF so you always choose the perfect format for your print or digital project.
Quick Comparison: SVG vs PNG vs PDF
| Feature | SVG (Vector) | PNG (Raster) | PDF (Vector) |
|---|---|---|---|
| Type | Mathematical Vector | Pixel Bitmap | Vector Document |
| Scaling | Infinite (Lossless) | Degrades when enlarged | Infinite (Lossless) |
| Best For | Graphic Design, Packaging | Web, Emails, Social Media | Direct Printing, Commercial Prepress |
| Transparency | ✅ Yes | ✅ Yes | ✅ Yes |
| Print Resolution | Perfect (300+ DPI) | Limited by pixel size | Perfect (300+ DPI) |
1. SVG (Scalable Vector Graphics) — The Designer’s Choice
SVG files define QR code modules as mathematical vector coordinates rather than colored grid pixels.
Infinite Scaling
Scale from a 1 cm watch face to a 10-meter highway billboard with zero loss in clarity.
Software Support
Open and edit paths directly in Adobe Illustrator, InDesign, CorelDRAW, and Figma.
Ultra Lightweight
Tiny file footprint (under 10 KB) ensures rapid rendering and instant page loads.
2. PNG (Portable Network Graphics) — The Web & Digital Standard
PNG is a lossless raster image format. It stores data as an exact matrix of pixels and supports alpha transparency.
- Best Used For: Website banners, slide presentations, email signatures, and mobile app interfaces.
- Limitation: Cannot be enlarged beyond its original pixel dimensions without suffering blur and pixelation.
3. PDF (Portable Document Format) — The Commercial Print Standard
PDF embeds clean vector geometry inside a standardized document container.
- Best Used For: Sending files directly to commercial print shops, signmakers, and packaging manufacturers.
- Advantage: Preserves exact dimensions in millimeters or inches, preventing accidental scaling shifts during prepress production.
Export Decision Matrix: Which Format Should You Choose?
- check Use SVG when designing in Figma, Illustrator, or Canva
- check Use PDF when emailing artwork directly to a print shop
- check Use PNG (1024×1024px+) for web and digital presentations
- close Never use low-res 72 DPI JPGs for physical print production
- close Don't scale up small PNGs (e.g. 200px) onto large posters
- close Don't remove the quiet zone margin when cropping exported assets
