FAQs

Frequently Asked Questions

Everything you need to know about FreeQRStore and generating QR codes.

Is FreeQRStore completely free to use?

Yes! All QR code generators on FreeQRStore are 100% free with unlimited scans and downloads. There are no subscriptions, hidden fees, paywalls, or limits on the number of QR codes you can generate.

Do I need to create an account or sign up?

No registration or login is required. You can instantly create, customize, and download your QR codes directly from your browser without providing personal details or an email address.

Are my QR codes private and secure?

Yes. FreeQRStore processes QR codes entirely client-side inside your web browser. Your sensitive inputs—such as Wi-Fi passwords, contact phone numbers, and vCard details—are never uploaded or saved to our servers.

Do the generated QR codes expire?

No. FreeQRStore generates standard static QR codes. Static QR codes encode the data directly into the pattern and do not rely on external redirection servers, meaning they never expire and remain functional forever.

What file formats can I download?

You can download your generated QR codes in high-resolution PNG format (ideal for screens and social media) or scalable vector SVG format (ideal for crisp, high-definition printing on business cards, menus, and posters).

Can I customize the colors of my QR code?

Yes. You can customize the foreground and background colors, select quiet zone margins, adjust dimensions, and pick your preferred error correction level (L, M, Q, H) to ensure optimal scan reliability.

How do static QR codes differ from dynamic QR codes?

Static QR codes embed your actual destination data (URL, text, Wi-Fi credentials) directly into the QR code matrix. Dynamic QR codes route through an intermediary server that can redirect links. Static QR codes never expire and cannot be disabled by a third-party subscription service.

Printing Advice

QR Code Printing & Scanning Best Practices

Color Contrast

Always maintain high contrast between foreground modules and the background. Dark foreground modules (such as black or deep navy) on a pure white background yield the fastest and most reliable camera scans.

Quiet Zone (Margin)

Never crop the quiet zone margin around the code. A clear boundary of at least 4 modules wide is needed by smartphone cameras to detect where the QR code starts and finishes.

Minimum Print Dimensions

For business cards and menus scanned at close distance (15–30 cm), print the QR code at least 2 × 2 cm (0.8 × 0.8 inches). For posters and banners viewed from further away, scale up proportionately.

Vector SVG for Print

When preparing files for professional commercial printing, always download the vector SVG format. SVGs scale to any size with zero pixelation or blurry edges.
