Is the QR code suitable for printing?
Yes — the generated image is 220×220 pixels, suitable for digital displays and small print. For large poster printing, SVG tools are recommended for better quality.
Do I need internet to scan a QR code?
Scanning the code with your camera does not need internet. But if the code contains a web link, you will need a connection to open it.
How much information can one QR code hold?
The maximum is approximately 4,296 alphanumeric characters. Less text means a clearer code that is easier to scan — short links are recommended.
Can a QR code expire?
A static QR code never expires. But if it links to a web URL that expires or changes, the link will stop working. The code itself remains valid forever.
How do I link a QR code to a business card?
Create a QR code with your LinkedIn page link, website or WhatsApp number in wa.me/+9685XXXXXXX format, then save and print it on your business card.
What is the difference between a QR code and a barcode?
A barcode is one-dimensional and holds only ~20 digits. A QR code is two-dimensional and holds thousands of characters. QR codes scan faster and work even when partially damaged.
Can I add a logo inside a QR code?
This tool generates codes without a logo. To add a logo, try QR Code Monkey or Canva — but a logo occupies part of the code and may reduce scan reliability.
What is the best size for printing a QR code?
The minimum for clear printing is 2×2 cm. For posters and stickers, 3–5 cm is recommended to ensure easy scanning with all types of cameras.
QR Code Generator — Uses and Best Practices

QR code size and scanning distance
For print use, a QR code should be at least 2 cm × 2 cm (roughly 0.8 × 0.8 inches). Scanning distance is approximately 10× the code size — a 3 cm code can be scanned from 30 cm away. Shorter URLs produce simpler codes that scan faster and more reliably.
