Frequently Asked Questions
What is a QR code?
A QR (Quick Response) code is a two-dimensional barcode that can store text, URLs, and other data. It can be scanned by smartphones and dedicated QR readers to quickly access the encoded information. QR codes can store up to 4,296 alphanumeric characters.
What can I encode in a QR code?
You can encode URLs, plain text, phone numbers, email addresses, Wi-Fi network credentials, calendar events, and more. For this tool, simply enter any text or URL and a scannable QR code will be generated.
What size should my QR code be?
For print, use at least 200×200 pixels. For digital use (websites, emails), 128–200 pixels is usually sufficient. Larger QR codes are easier to scan from a distance. Ensure there is adequate contrast between the code and its background.
Can I use any color for my QR code?
While you can use any color, the QR code must have sufficient contrast with its background to be scannable. Dark colors on a light background work best. Avoid light colors on white backgrounds or dark colors on dark backgrounds.
About QR Codes
QR codes were invented in 1994 by Denso Wave, a Japanese automotive company. They were originally used to track vehicles during manufacturing but have since become ubiquitous in marketing, payments, and information sharing. The QR code's ability to be read quickly (hence "Quick Response") and its error correction capability make it ideal for real-world use.
Error Correction Levels
QR codes include built-in error correction that allows them to be read even when partially damaged or obscured. Our generator uses a standard level that can recover up to 25% of the code if damaged.
