QR Code Generator
About the QR Code Generator
QR codes have become an essential tool for sharing information quickly and efficiently. Whether you need to share a website URL, contact information, Wi-Fi credentials, or any other text data, QR codes provide an instant way for users to access that information simply by scanning with their smartphone camera.
Our free QR code generator creates high-quality codes entirely in your browser. No data is sent to any server, ensuring your privacy is protected. You can customize the size of your QR code from 100 to 400 pixels, making it suitable for various applications from digital displays to printed materials.
The error correction feature is particularly important for QR codes that will be printed or displayed in environments where they might be partially obscured or damaged. Higher error correction levels allow the code to remain scannable even when up to 30% of it is damaged or covered. However, higher error correction also increases the density of the code, so choose the level appropriate for your use case.
For best results when printing QR codes, ensure adequate contrast between the code and background, and maintain a quiet zone (white space) around the code. The generated PNG format is suitable for both digital and print applications. For large format printing, consider generating a larger size to maintain scanning reliability.
