What is a QR code?
A QR code (Quick Response Code) is a two-dimensional barcode that encodes data as a grid of black and white squares. Smartphone cameras can decode them instantly. A single QR code can hold a URL, plain text, an email address, a phone number, Wi-Fi credentials, or contact card data.

Things to consider when creating QR codes
Error correction level
QR codes can still be scanned even when partially damaged. Higher error correction (H = 30% data recovery) makes codes more resilient. Use H-level if you plan to overlay a logo or use the code on physical printed materials.
Minimum print size
For printed QR codes, a minimum size of 2.5 cm × 2.5 cm (about 1 inch) is recommended. Too small and scanners struggle. Set pixel dimensions generously for digital use.
Always test before distributing
Test the QR code with multiple devices and QR scanner apps before printing or publishing. A QR code that can't be scanned defeats its purpose.
Frequently asked questions
Are QR codes free to create?
Yes. The ProUtils QR Code Generator is completely free with no account required.
Do my QR codes expire?
Static QR codes (where the URL is encoded directly) never expire. Dynamic QR codes through URL shorteners can be updated later, but depend on the shortener service staying active.
How much data can a QR code hold?
QR codes can hold up to around 3 KB of data, which is sufficient for URLs and short text. For longer content, use a URL shortener to link to a page.
