A real decoder, not a guess
Each time you change a color, shape or logo, we render the code and read it back with the same kind of decoder phones use. You see the result right next to the preview.
Every QR code tested before you print
Nothing is worse than 10,000 flyers with a code that doesn't scan. We test every design with a real QR decoder while you edit.

Questions
- Does the test guarantee my print will scan?
- It guarantees the design itself is readable. Print size, paper and lighting matter too — print at least 2 × 2 cm and test the printed result once.
- Why did my design get a warning?
- Usually low contrast or a large logo. Follow the suggestion next to the preview and the warning disappears.
