Q1: What is a QR code and how does it work?
A QR (Quick Response) code is a two-dimensional barcode that can store various types of data (text, URLs, contact info, etc.). When scanned with a smartphone camera or QR reader app, it instantly decodes the information. QR codes are widely used for sharing links, contact details, Wi-Fi credentials, and more.
Q2: What can I encode in a QR code?
You can encode: URLs/websites, plain text, contact information (vCard), email addresses, phone numbers, SMS messages, Wi-Fi network credentials, and more. This generator accepts any text input, making it suitable for URLs, simple text, or formatted data strings.
Q3: How do I scan a QR code?
Most modern smartphones have built-in QR code scanning in their camera apps. Simply open your camera app, point it at the QR code, and tap the notification that appears. Alternatively, download a QR code scanner app from your app store. The phone will automatically decode and open the content.
Q4: Can I customize the QR code appearance?
This generator creates standard black-and-white QR codes with default settings. For customization (colors, logos, error correction levels), you'd need more advanced QR code generators. The standard format works for all QR scanners and ensures maximum compatibility.
Q5: How much data can a QR code store?
QR codes can store: up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes of binary data. The actual capacity depends on the error correction level and version. For most use cases (URLs, short text), standard QR codes have plenty of capacity.
Q6: Is my data secure when generating QR codes?
QR code generation happens entirely in your browser - no data is sent to any server. The QR code is generated locally on your device. However, remember that anyone who scans the QR code can see the encoded information, so don't encode sensitive data in publicly accessible QR codes.
