QR Code Validator — Check Before You Print
Upload your QR code image to verify it scans, the destination URL is live, and there are no broken redirects. Free, no account required.

The QR image is decoded in your browser. Only live URL checks call our secure validator endpoint.
Validate a QR code before it reaches print, packaging, or signage
A QR code validator answers a different question than a basic scanner. Instead of only decoding the payload, it helps you check whether the code is actually ready to ship. That matters when a printed QR code will appear on flyers, labels, menus, posters, packaging, or storefront materials where every failed scan costs trust and attention.
This validator checks five practical signals in one pass: whether the image decodes, whether the destination URL responds, whether the QR version is dense enough to become risky at small sizes, whether the content uses secure HTTPS, and whether the final redirect stays on the domain you expect. Those checks cover most of the common pre-launch mistakes teams make.
Because the image itself is decoded locally in your browser, you can test screenshots, exported artwork, or proofs without uploading the QR asset. If the code contains a web link, the validator also calls our secure resolution endpoint to inspect the final destination and redirect chain before you print thousands of copies.
Frequently asked questions about QR code validation
What does a QR code validator check?
This validator checks whether the QR code scans, whether the destination URL responds, how dense the QR version is, whether the payload uses HTTPS, and whether redirects stay on the expected domain.
Can I validate a QR code from an image file?
Yes. Upload a PNG, JPG, WEBP, or GIF, drag and drop it, or paste a copied screenshot. The QR image is decoded directly in your browser.
What is a good QR version for print?
Lower versions are easier to scan at smaller physical sizes. Version 1-10 is usually safest, version 11-20 deserves a print-size check, and version 21-40 is dense enough to create scanning friction when printed small.
Why does the validator warn about HTTP?
HTTP links are not encrypted. If your QR code leads to a web page, HTTPS is the safer default because it protects users and avoids browser trust issues.
Why does a redirect warning matter?
Redirects are not always bad, but they add another moving part. A warning tells you the QR does not land directly on the destination and may end on a different domain than the one encoded in the QR.
Can this tool detect phishing or malware?
No. This version validates scan quality, URL reachability, and redirect behavior. It does not run external threat-intelligence checks against the destination.
Is the QR image uploaded to your server?
No. The QR image is decoded in your browser. Only URL validation requests are sent to the `/api/tools/resolve-url` endpoint when the QR contains an HTTP or HTTPS link.
