Inspect the information encoded in a QR screenshot or design file, then distinguish decoding from checking destination trust.
You have a QR code in a screenshot or design proof and want to know what it contains. A reader can decode the image without pointing a second device at the screen. This is useful when reviewing your own print artwork.
Start with a clear image
Include the entire pattern and surrounding border. Avoid cutting off corners or stretching the image. Use the original downloaded code instead of a low-quality screenshot where possible.
- Open the QR code reader.
- Choose an appropriate supported image.
- Inspect the decoded result.
- Compare your own code with its intended address or text.
- Test the printed version separately.
A successful decode from a clean file does not prove a glossy label will scan from the intended distance. Digital and physical tests answer different questions.
Read before following the link
The payload may contain a URL, contact data or another kind of text. Examine an address and its context before opening it. Successful decoding does not establish that a destination is trustworthy.
A short address may redirect elsewhere. For a link you manage, the redirect checker can help inspect that route, followed by a browser check of the final content.
Fix the correct problem
If the encoded address is wrong, editing the poster caption will not repair it. Create the correct code or change a managed destination you control. If the address is correct but the print fails, investigate the physical design.
Do not upload a private invitation or access code to a public tool when a local process would be more appropriate. Encoded information can still be sensitive.
Try the reader with your own public design. Follow the scanning troubleshooting guide, or create a r37dy account to prepare a replacement.
