SVG vs PNG for QR codes: which one should you download?

When SVG is mandatory (printing), when PNG is fine (screens), and how resizing affects scan reliability.

QR codes fail more often because of blurry edges than because of “wrong data”. File format matters.

Use SVG when…

  • You will print (business cards, menus, posters, signage).
  • You will resize in design tools (Figma/Illustrator/Canva/InDesign).
  • You need perfectly sharp module edges at any size.

Use PNG when…

  • You only need the QR for screens (web page, slides, emails).
  • You will not resize much (or you export at a sufficiently high resolution).

The common mistake

People download a small PNG (e.g. 256×256) and then scale it up for print. That introduces blur and aliasing. Blur reduces the scanner’s ability to detect module boundaries.

Print-ready rule of thumb

Print: SVG (recommended)
If you must use PNG, export at high resolution (at least 1000px+) and do not upscale further.

Also make sure you keep enough margin (quiet zone) and good contrast. See: contrast + quiet zone guide.
