About This Tool
Generate QR codes for URLs, plain text, WiFi credentials, email addresses, phone numbers, and more. Customize the size, error correction level, and colors. The generated QR code can be downloaded as a high-resolution PNG image suitable for both digital display and print use.
Frequently Asked Questions
- What error correction level should I use?
- Level L (7% recovery) for clean digital displays, M (15%) for general use, Q (25%) for printed materials, and H (30%) if the QR code may be partially obscured or if you want to add a logo overlay.
- Is there a limit to how much data a QR code can hold?
- A standard QR code can store up to 7,089 numeric characters, 4,296 alphanumeric characters, or 2,953 bytes. However, more data means a denser, harder-to-scan code. Keep URLs short for best results.
- Can I generate WiFi QR codes?
- Yes. Enter your network name (SSID), password, and security type (WPA/WPA2/WEP). When scanned, the QR code will automatically connect the device to your WiFi network.
- Will the QR code work for print materials?
- Yes. Download at the largest available size. For print, use at least 2cm × 2cm (0.8in × 0.8in) at 300 DPI. The QR code should have sufficient contrast and a quiet zone (white border) around it.
