URL Checker with QR Code – Verify Safe Links
Check if a link is safe before generating a QR Code. Detects HTTPS, redirects, and blacklists.
🛡️ URL Checker QR Code
Step 1: Enter a secure URL
Paste the full URL you want to check. It must start with https:// to ensure security.
Step 2: Click on “Check”
Click the “Check” button to validate the link. The system will analyze redirections, HTTPS status, and blacklist protection (Google Safe Browsing).
Step 3: QR Code is generated automatically (if safe)
If the URL is valid and safe, the QR Code is generated instantly. If it's insecure or blacklisted, the QR Code will be reset to the default placeholder.

More About URL Checkers and Secure QR Code Generation
- 🔒 Check if the URL uses HTTPS
- 🚫 Search for the domain in blacklists
- 🔄 Follow and verify redirects
No. For safety, only HTTPS URLs are accepted. Non-secure (HTTP) links are blocked automatically.
2. What happens if a URL is blacklisted?
If the domain is flagged by security databases, the QR Code is not generated. This helps prevent malware or phishing attacks.
3. Is this service free?
Yes, the URL verification and secure QR generation are free to use. No registration is required.
4. Can I customize the QR Code after checking the URL?
Absolutely! You can apply colors, shapes, and logos — as long as the QR remains scannable.
5. Can I track if someone scanned my verified QR?
Only dynamic QR Codes allow scan tracking. The secure URL checker generates static codes, which are permanent but not trackable.
What if the destination of a safe URL changes later?
If the destination becomes unsafe after the QR is created, we can't block it retroactively. Always monitor your links if security is critical.
Can a safe link later be flagged?
Yes. Blacklist databases are updated frequently. A previously safe link may be flagged later due to new risks or reports.
Does Code2Scan follow redirects?
Yes. We check final redirection destinations and only allow QR generation if the entire chain is secure and HTTPS-based.
What types of sites are commonly blocked?
Adult content, gambling, phishing, malware, and known spam landing pages are most frequently blocked.
Does the QR Code work if the original URL is deleted?
The QR will still scan, but users will see a 404 or error page unless you’re using a dynamic link with redirect fallback.
