QR Code Diagnostic: Detect Malicious Links & Phishing Instantly
Why check a QR code before scanning it?
Malicious QR codes are a growing threat: they can redirect to phishing sites, trigger malware downloads or steal your credentials. Our free QR code diagnostic analyzes every URL in depth before you risk a single click — no installation, no registration required.
How does the security analysis work?
Our diagnostic engine simultaneously inspects multiple signals: known phishing domains, shortened URLs masking the real destination, insecure HTTP protocols, suspicious subdomains, deceptive encoded characters, and typical typosquatting attack patterns. The security score is calculated in real time.
100% Local Analysis & Privacy Protection
The entire diagnostic runs in your browser. No URL, no data is ever sent to our servers. Your privacy is protected with every analysis — check as many links as you want, free and fully confidential.
