Frequently Asked Questions
What can I encode in a QR code?
QR codes can encode various types of data including website URLs, plain text, contact information (vCard), WiFi network credentials, phone numbers, email addresses, SMS messages, and geographic locations.
Can I customize the appearance of my QR code?
Yes, our generator allows you to customize colors, add a logo or image to the center, adjust corner styles, and select different patterns while ensuring the QR code remains scannable.
What's the best image format for downloading QR codes?
For digital use, PNG format is recommended as it supports transparency. For print materials or high-resolution needs, SVG format is best as it can be scaled to any size without losing quality.
How do I ensure my QR code is scannable?
To ensure scannability, maintain adequate contrast between foreground and background colors, don't overcrowd the QR code with a large logo, use higher error correction levels for customized codes, and test your QR code with multiple scanning apps.
Are there size limitations for QR codes?
The physical size of a QR code can vary, but it should be large enough to be easily scanned. For printed materials, a minimum size of 2 x 2 cm (0.8 x 0.8 inches) is recommended, with larger sizes needed for codes that contain more data.
