A QR code stores data such as a URL or short text in a pattern that a camera can scan. Keep the encoded content concise, choose a size that will remain legible after printing, and test the final image with a phone.
Create a scannable code
Long URLs and dense content make QR patterns harder to scan, especially when the image is printed small or displayed with low contrast.
- Paste the exact link or text to encode.
- Generate the QR image and choose a useful output size.
- Scan the exported image on a second device.
- Confirm that it opens the intended destination before distributing it.
Keep in mind: A QR code does not make a destination trustworthy. For public materials, use a recognizable domain and keep the destination stable.
