What is error correction in QR codes?

Error correction allows a QR code to be scanned even if part of it is damaged or obscured. Level L recovers 7% of data, M recovers 15%, Q recovers 25%, and H recovers 30%. Higher levels make the QR code denser but more resilient.

What is the maximum data a QR code can store?

A QR code 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 — higher correction reduces capacity.

Can I use custom colors in QR codes?

Yes, you can customize foreground and background colors. Ensure sufficient contrast between them for reliable scanning. Dark foreground on light background works best. Avoid transparent backgrounds.

What is the difference between PNG and SVG formats?

PNG is a raster format — ideal for web use and sharing at a specific size. SVG is a vector format — it scales to any size without quality loss, making it perfect for print materials, signage, and large-format displays.

How do I create a Wi-Fi QR code?

Select the Wi-Fi preset, then enter your network name (SSID), password, and security type (WPA/WPA2/WEP/None). The QR code encodes the standard WIFI: format that Android and iOS can scan to auto-connect.
