Question 1

Are these generated QR codes safe to use?

Accepted Answer

Yes, our tool generates static client-side QR codes. We do not store your payload data or redirect through intermediate tracking servers, ensuring 100% privacy and security.

Question 2

What is the difference between Static and Dynamic QR codes?

Accepted Answer

Static QR codes encode data directly into the pattern and work forever without expiring. Dynamic QR codes redirect through a short URL, allowing content updates and analytics tracking.

Question 3

Can these generated QR codes ever expire?

Accepted Answer

No. All QR codes generated using this tool are static and embedded directly with your data, meaning they will function indefinitely without requiring any subscription.

Question 4

What is the optimal size for a printed QR code?

Accepted Answer

For small items like business cards, a minimum size of 2x2 cm (0.8x0.8 inches) is recommended. For posters and banners, calculate the size based on a 10:1 scanning distance ratio.

Question 5

What is the minimum recommended print size?

Accepted Answer

The absolute minimum print size for standard smartphone cameras is 2 cm x 2 cm (approx. 0.8 inches) with clear high-contrast borders.

Question 6

Can I edit or change the destination URL later?

Accepted Answer

Static QR codes store destination data permanently within the pixel matrix. To change the link later, you must generate a new static QR code or use dynamic QR routing.

Question 7

Do QR codes work offline without an internet connection?

Accepted Answer

Yes! Static QR codes containing plain text, contact vCards, phone numbers, or WiFi login details can be decoded by smartphones completely offline.

Question 8

Can a QR code automatically connect to WiFi or store passwords?

Accepted Answer

Yes. Encoded WiFi QR codes contain network credentials (SSID and Password) allowing iOS and Android devices to join the network automatically upon scanning.

Question 9

Why should I download QR codes in SVG format?

Accepted Answer

SVG is a vector graphics format that can be scaled up infinitely to any billboard or packaging print dimension without losing sharpness or becoming pixelated.

Question 10

How does Error Correction work in custom QR codes?

Accepted Answer

Error Correction adds redundant data blocks (up to 30% in High mode), allowing the QR code to remain fully readable even if dirty, damaged, or partially covered by a logo.
