What types of QR codes can be generated?

Multiple types are supported: URL, plain text, email, phone number, SMS, WiFi connection, VCard, Alipay/WeChat Pay QR codes, and more. Different types support different functions and data capacity.

Can I customize the QR code appearance?

Yes, rich customization options are supported: foreground and background colors, color gradients, rounded/square corners, adding logo images, hiding partial data points to create unique styles. Personalized QR codes maintain scanning performance while being more brand recognizable.

What is the effective scanning distance for QR codes?

Scanning distance depends on QR code size and data density. General rule: QR code size should be at least 1/10 of scanning distance. For example, to achieve 1-meter scanning, QR code size should be at least 10x10 cm. We recommend leaving sufficient size margin in actual use.

What output formats are supported for generated QR codes?

Supports PNG (web use), SVG (vector printing), PDF (document embedding), EPS (professional design) formats. SVG is the recommended format, losslessly scalable to any size, suitable for printing and high-definition output needs.

Is there a limit on QR code data capacity?

QR code capacity depends on version (version 1-40) and error correction level. Version 40 can store up to about 4000 numeric characters. However, more data means denser QR code and increased scanning difficulty. We recommend keeping URL content under 500 characters.

How to test if the QR code is working?

The system provides built-in scanning test function. You can use your phone to scan the QR code on the page to verify if the content displays correctly. During testing, ensure the QR code is clear, complete, and not obscured or blurred.
