Create useful and reliable QR codes
Choose the correct QR content type, keep the payload concise and test the result on another device.
Choose the correct content type
A web address, Wi-Fi network, contact card and calendar event use different payload formats. A dedicated generator reduces typing errors and improves compatibility.
Keep enough contrast
Use a dark foreground on a light background and preserve the quiet margin around the code. Decorative changes can reduce readability.
Test before publishing
Scan the downloaded image from another device and confirm the decoded destination. Static QR codes cannot be changed after printing.
