Choose the right format
- PNG: an image for websites, social media, emails and documents.
- SVG: a vector file that stays sharp at any size. Best for print shops, signs and design tools like Canva, Illustrator or Figma.
- PDF: ready to print, or to send to a printer.
What size to print
A simple rule: the code should be at least one tenth of the scanning distance. For a business card or a table, 2 to 3 cm (about 1 inch) is enough. For a poster read from 2 meters away, aim for 20 cm.
Codes with more content, such as long texts or full vCards, are denser and need to be printed larger.
Test before printing
- 1Open the downloaded file on another screen, or print a single test copy.
- 2Scan it with an iPhone and an Android phone.
- 3Check that it opens the right link, network, contact or message.
- 4Try scanning from the distance and the lighting where it will be used.
Printing tips
- Use matte paper when possible: glossy surfaces reflect light.
- Don't stretch the code; resize it proportionally.
- Keep the white margin around the code.
- Avoid placing the code on a curve or a fold.
