CWA Infotech - QR Code Generator

A QR code (Quick Response code) is a type of matrix barcode that contains information about the item to which it is attached. QR codes can store various types of data, such as website URLs, contact information, and plain text.

Most modern smartphones have built-in QR code scanners in their camera apps. Simply open your camera app, point it at the QR code, and a notification should appear. Alternatively, you can download a QR code scanner app from your app store.

Yes, our QR code generator allows you to customize the colors, add a logo, choose different styles, and adjust the size and error correction level. However, be careful not to make the QR code too complex, as it might affect scannability.

For digital use, PNG is usually sufficient. If you plan to resize your QR code or print it in large formats, SVG is better as it's a vector format that won't lose quality when scaled. PDF is good for documents and printing purposes.

Error correction allows a QR code to be readable even if a portion of it is damaged or obscured. Higher error correction levels make the QR code more resilient but also more complex. If you're adding a logo to your QR code, it's recommended to use a higher error correction level (H - 30%).
