Frequently Asked Questions.
Clear answers about our dynamic QR technology, vector exports, scannability standards, and honest pricing model.
Can I change the destination of a QR code after printing?
Yes. With QRHQ Dynamic QR codes, you can change the target URL, PDF menu, or landing page anytime in your dashboard without changing or reprinting the physical QR code.
Do QRHQ QR codes ever expire or get held hostage?
No. QRHQ operates on a strict Zero-Hostage Guarantee. Unlike legacy QR providers that deactivate your printed codes after a 14-day trial, QRHQ ensures your codes remain permanently active and accessible.
What file formats can I download for professional printing?
QRHQ provides mathematical 300 DPI vector formats including SVG, EPS, and high-resolution PNG (up to 2048px). Vector files can be scaled to any size for billboards, packaging, and table tents without pixelation.
How does center logo error correction work?
When you embed a logo or brand icon into a QR code, QRHQ automatically enforces Error Correction Level H (30% redundancy). This guarantees that smartphone cameras scan the code instantly even with a prominent center logo.
How fast is QRHQ dynamic redirection?
QRHQ redirects through a global Anycast Edge network with edge KV routing, delivering near-instant sub-5ms redirection worldwide so your visitors never experience loading delays.
Can I route visitors by mobile device (iOS vs Android)?
Yes. Dynamic Smart Rules let you specify separate destination URLs for iOS, Android, and Desktop visitors from a single QR code on your product packaging or poster.
Is scan analytics privacy-friendly (GDPR / CCPA compliant)?
Yes. QRHQ uses zero tracking cookies and anonymizes IP addresses at the edge. You receive accurate country, city, OS, and timestamp telemetry without collecting personally identifiable information (PII).
How many dynamic QR codes can I create on the Pro plan?
The Pro plan offers Unlimited Dynamic QR codes with no monthly scan caps and full access to smart routing rules and vector export formats.
