QR Code Generator

A QR (Quick Response) code is a two-dimensional barcode that can be scanned using smartphone cameras or QR code readers. It stores information such as URLs, text, and contact information, allowing quick access to digital content.

Most modern smartphones have built-in QR code scanning capabilities in their camera apps. Simply open your camera app, point it at the QR code, and your phone should recognize it automatically. Some older phones may require a dedicated QR code scanner app.

Error correction allows a QR code to be readable even if part of it is damaged or obscured. Higher error correction levels make the QR code more resilient but also increase its complexity and size. The levels available are:

• Low (L): Approximately 7% of the code can be restored
• Medium (M): Approximately 15% of the code can be restored
• Quartile (Q): Approximately 25% of the code can be restored
• High (H): Approximately 30% of the code can be restored

The ideal size depends on how and where your QR code will be used. As a general rule:

• For print materials (business cards, flyers): A minimum of 2 cm × 2 cm
• For posters or signs meant to be scanned from a distance: About 10% of the total scanning distance (e.g., a QR code to be scanned from 2 meters away should be at least 20 cm × 20 cm)
• For digital display: At least 100 × 100 pixels

Remember that our tool allows you to download high-resolution QR codes that can be sized appropriately for your specific use case.

This free version of our QR Code Generator does not include logo embedding functionality. However, you can customize the colors to match your brand identity. For logo embedding and advanced customization options, you might need to use specialized QR code services.

Yes, QR codes have character limits depending on the type of data and error correction level:

• Numeric only: Up to 7,089 characters
• Alphanumeric: Up to 4,296 characters
• Binary (8-bit bytes): Up to 2,953 characters
• Kanji/Kana: Up to 1,817 characters

However, for optimal scanning speed and reliability, we recommend keeping your content as concise as possible, especially for URLs and text.

Medium (M) error correction is suitable for most standard uses. Choose Higher levels (Q or H) if you expect your QR code to be used in environments where it might get damaged or partially obscured (e.g., outdoor settings, printed materials subject to wear and tear, or if you plan to add visual elements like rounded corners or a small logo later).
