QR codes hide the destination until you scan them
QR codes are convenient, but the image itself does not tell you where it leads. Before printing a code, sharing it in a campaign, or opening a code from an unknown source, it is useful to inspect the stored text or URL directly.
Use the QR Code Reader to decode QR codes from images and screenshots in the browser.
What to check before publishing a QR code
Verify that the code points to the intended production URL, not a staging page. Check that UTM parameters are present if the link is part of a campaign. Also test the QR code at the size where it will appear in print or on screen.
If you are creating a new code, generate it with the QR Code Generator and then read it back before publishing.
Why scanning can fail
Small, blurry, low-contrast, cropped, or tilted QR codes can be difficult to read. Leave margin around the code, keep the contrast high, and avoid placing it over busy backgrounds.
Summary
Generating a QR code is only half the workflow. Reading it back before launch helps catch wrong URLs, missing tracking parameters, and print-quality problems while they are still easy to fix.
