What to Encode
For a simple website link, encode the full URL including https:// — don't abbreviate to www or omit the protocol. If you have UTM tracking parameters to add, include them in the URL before generating the code so analytics can distinguish QR-originated traffic.
Size and Format Recommendations
Generate your QR code at a minimum of 300x300 pixels for digital use. For print, export as SVG or at least 1000x1000 pixels to ensure sharp rendering at any printed size. The QR code should be at least 1cm per unit of scanning distance.
Quiet Zone Matters
The quiet zone — the white border around the QR code — is mandatory for reliable scanning. Maintain a minimum of 4 modules of white space on all sides. When placing QR codes in designs, ensure background elements don't encroach on this border.
Test Before Publishing
Always test your QR code with multiple devices (iOS, Android) and under realistic conditions — printed at intended size, photographed from the expected scanning distance with typical lighting. Generate, print a proof, test, then finalize.
Generate your website QR code at high resolution, include quiet zone, test at final size before printing, and track QR-originated traffic with UTM parameters.
