Frequently Asked Questions

What are QR codes and how do they work?

QR codes (Quick Response codes) are 2D barcodes that store information in a square pattern of black and white modules. They can be scanned by smartphone cameras or dedicated QR code readers to quickly access the encoded information, such as websites, text, or contact details.

What's the maximum amount of data a QR code can store?

QR codes can store up to 3,000 alphanumeric characters, 7,000 numeric characters, or about 1,800 bytes of binary data. However, for optimal scanning, it's recommended to keep content concise, especially for URLs and text.

What does error correction level mean?

Error correction allows QR codes to be readable even if they're partially damaged or obscured. Higher levels (H=30%) can withstand more damage but create denser QR codes. Medium (M=15%) is suitable for most applications.

Can I use custom colors for my QR code?

Yes, you can customize both foreground and background colors. However, ensure sufficient contrast between colors for reliable scanning. Dark colors on light backgrounds typically work best.

Do QR codes expire or stop working?

Static QR codes (like those generated by this tool) don't expire and will work indefinitely. However, if the QR code links to a URL, that website must remain active for the QR code to be useful.

What's the best size for printing QR codes?

For print materials, QR codes should be at least 2x2 cm (0.8x0.8 inches) for business cards and larger for posters or signage. The rule is: the further the scanning distance, the larger the QR code should be.

Can smartphones scan all types of QR codes?

Most modern smartphones can scan standard QR codes directly through their camera apps without additional software. However, some special functions like WiFi auto-connect may require specific QR code reader apps depending on the device.

Is my data secure when using this QR generator?

Absolutely. All QR code generation happens entirely in your browser using JavaScript. Your data is never transmitted to our servers or any third-party services, ensuring complete privacy and security.
