Frequently Asked Questions

What is a QR code?

A QR (Quick Response) code is a two-dimensional barcode that can store data like URLs, text, WiFi credentials, contact info, and more. Smartphones can scan them instantly using their camera.

Is this QR code generator free?

Yes, 100% free with no sign-up required. Generate unlimited styled QR codes directly in your browser. Nothing is sent to any server.

What types of QR codes can I create?

You can generate QR codes for website URLs, plain text, WiFi network credentials, email addresses (with subject/body), phone numbers, SMS messages, and vCard contact details.

What is a vCard QR code?

A vCard QR code encodes contact information — name, phone numbers, email, address, company, and website. When scanned, it allows the person to save your contact details directly to their phone.

Can I customize the QR code style?

Yes! Open "Advanced Configurations" to choose dot shapes (rounded, dots, classy, etc.), marker styles, gradient fills with custom colors, and even overlay your logo in the center.

What is error correction level?

Error correction allows a QR code to be read even if partially damaged or obscured. Higher levels (like H = 30%) make the code more resilient but denser. Use "High" when adding a logo overlay.

What size should I download?

512×512px works for most digital uses. For print materials (business cards, posters), use 1024×1024 or 2048×2048. The download will be at the exact resolution you select.

Do the QR codes expire?

No. QR codes are just encoded data — they never expire. As long as the URL or content they point to exists, they'll keep working forever.
