QR Code Best Practices
- 1Always test your QR code with multiple scanning apps (like iPhone Camera and Google Lens) before printing it on physical materials.
- 2Don't make it too small. Physical QR codes should generally be at least 1 x 1 inch (2.5 x 2.5 cm) to be easily scannable from a standard distance.
- 3Maintain a quiet zone. QR codes need clear space (margins) around them so cameras can easily detect their borders.
- 4Link to mobile-friendly pages. Since almost all QR codes are scanned via mobile devices, it's critical that the destination URL is responsive and loads quickly on phones.
QR Code Generator FAQ
Do these QR codes expire?
No. The QR codes generated here are 'Static QR Codes'. They directly encode your text or URL and will work forever, as long as the destination URL or text remains valid.
Can I edit the destination of the QR code later?
No. Static QR codes cannot be edited once generated. The pattern relies directly on the exact characters you enter. If you need to change a destination frequently, you would need a 'Dynamic' QR code service.
Is this tool free for commercial use?
Absolutely. You can generate as many QR codes as you like and use them on your business cards, flyers, websites, or products without any fees.
Are there any privacy concerns?
Our QR codes are generated entirely locally in your browser. We do not track your inputs, nor do we track the people who scan your QR codes.
What is the best color for a QR code?
For maximum scanability by all devices, high contrast is key. A black QR code on a white background is the safest choice. If you customize colors, ensure the foreground (QR pattern) is significantly darker than the background.
