⚡ Why StaqTools QR Generator?
There are dozens of QR generators online — but most are overloaded with ads, require logins, or limit downloads.
Here’s why StaqTools QR Generator stands out:
- ✅ 100% Free — no account, no watermark
- ✅ Supports Text, URLs, Emails, Numbers, Wi-Fi, and more
- ✅ Fast, clean UI — made for speed

🔒 Do QR Codes Expire?
Most QR codes generated from static data (like URLs or plain text) never expire. Dynamic QR codes with analytics or tracking links may have expiration rules — but tools like StaqTools generate static codes, ensuring forever-valid links.
🎯 SEO + Accessibility Tips for Using QR Codes
If you’re embedding QR codes into websites or docs, remember:
- Always use alt text for accessibility (e.g.,
alt="QR code to dev build"). - Consider placing short URLs next to QR codes for fallback.
- Use high-contrast color codes (black on white is best for scanners).
- Optimize image size under 500 KB for faster loading.
