Frequently Asked Questions

A QR code generator is an online tool that creates Quick Response (QR) codes - two-dimensional barcodes that store information like URLs, text, contact details, WiFi credentials, and more. When scanned with a smartphone camera or QR code scanner app, it instantly provides access to the encoded information. Our free QR code generator creates both static and dynamic QR codes using advanced encoding algorithms to ensure perfect scannability.

The best free QR code generator offers unlimited static QR codes, dynamic QR code options, full customization (colors, logos, frames), multiple QR code types (URL, WiFi, vCard, PDF), high-resolution downloads, and analytics.

Static QR codes contain fixed, permanent information that cannot be changed after creation - ideal for WiFi passwords, vCards, or permanent URLs. Dynamic QR codes use a short redirect URL, allowing you to update the destination content anytime without reprinting the code. Dynamic QR codes also provide detailed scan analytics, location tracking, and A/B testing capabilities, making them perfect for marketing campaigns and business use.

Users can scan the WiFi QR code to connect automatically without typing passwords. Perfect for businesses, restaurants, hotels, and home networks.

Yes, our secure QR codes use enterprise-grade SSL encryption, GDPR compliance, and follow security best practices. Dynamic QR codes include password protection, expiration dates, and scan limits for added security.

Our dynamic QR codes include comprehensive analytics: real-time scan tracking, geographic location data, device types (iOS/Android), scan timestamps, unique vs. repeat scans, conversion tracking, and detailed reports.

Our bulk QR code generator allows you to create hundreds or thousands of QR codes at once. Simply upload a CSV file with your data (URLs, text, vCards), select your customization preferences, and generate all QR codes simultaneously. Bulk generation is perfect for product labeling, event tickets, inventory management, and large-scale marketing campaigns. Available in Pro and Enterprise plans.

For optimal scanning, QR codes should be at least 2 x 2 cm (0.8 x 0.8 inches) in print. The ideal size depends on scanning distance: for business cards use 2-3 cm, for posters use 5-10 cm, for billboards use 50+ cm. Our generator creates high-resolution QR codes (up to 4096px) suitable for any print size. Always test your printed QR codes before mass production.

Static QR codes containing text, contact information (vCard), WiFi credentials, or calendar events work completely offline. However, URL QR codes, dynamic QR codes, and codes linking to online content require internet connectivity to access the destination. The scanning process itself works offline, but accessing the content may need internet.

Static QR codes never expire and work permanently - they contain fixed data directly in the code. Dynamic QR codes require an active subscription to maintain functionality and analytics. Our free plan provides unlimited permanent static QR codes. You can also set custom expiration dates for dynamic QR codes to control access for time-limited campaigns or promotions.

To create a vCard QR code: 1) Select 'vCard' type, 2) Enter contact details (name, phone, email, company, website, address), 3) Add your photo (optional), 4) Customize design, 5) Generate and add to business cards. When scanned, the vCard QR code instantly adds your contact information to the user's phone, making networking seamless and eco-friendly.
