Frequently Asked Questions
What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that can be scanned by smartphone cameras and dedicated readers. It encodes data as a pattern of black and white squares.
What data can a QR code store?
QR codes can store URLs, plain text, email addresses, phone numbers, Wi-Fi credentials, and more. The maximum capacity is around 4,296 alphanumeric characters, though smaller payloads produce more reliable scans.
What size should my QR code be?
For print, the QR code should be at least 2 cm × 2 cm (about 0.8 in) for close-range scanning. For posters or signage scanned from a distance, scale up proportionally. The SVG format is ideal for print as it scales without losing quality.
Is this generated locally?
Yes. The QR code is generated entirely in your browser. No data is sent to any server.
