QR testing lab
Catch the boring mistakes before they become expensive ones.
Check colours, build a clean campaign link and inspect the final QR image. Everything here runs in the browser without an account.
Find out what your QR code is doing.
Upload or photograph a QR code. We decode the image privately in your browser, then check any web address for redirects, security and destination errors.
Open toolColour checkCheck QR colours before they reach the printer.
Choose the two colours you plan to use. This quick check flags weak contrast and reversed light-on-dark artwork.
Open toolCampaign linkBuild a campaign URL without hand-editing the query string.
Add the source, medium and campaign name, then download a fixed QR or carry the tagged link into an editable HonestQR campaign.
Open toolPrivate image checkRun a quick preflight on the QR image you plan to print.
The file stays in your browser. We check whether it decodes, its pixel size, approximate contrast and whether the outer edge looks clear.
Open toolStill test the real thing
A browser check cannot reproduce paper, glare or distance.
Use these tools as a preflight, then print one copy at final size and scan it with more than one phone.
