Important Notes (Must Read)
- This is a Static QR Code：Once generated, the content in the QR code cannot be modified. If the link or information is wrong, you need to generate a new one.
- Cannot Track Data：QR codes generated by this tool cannot track scan counts, locations, etc. This feature is typically provided by paid dynamic QR code services.
- Logo and Color Impact：Overly complex or oversized logos, and low contrast between foreground and background colors, may make the QR code difficult to recognize. Be sure to test with multiple devices.
- WeChat Scan Compatibility：WeChat's 'Scan' has limited support for standard QR codes. URL type is fully compatible; but for text, WiFi, email, vCard types, WeChat may not recognize or invoke corresponding functions. For best experience, use phone's built-in camera to scan.
Terminology
- Error Correction Level
- Refers to the QR code's ability to be correctly scanned after being partially obscured or damaged. Higher levels provide stronger resistance to obstruction but can store less content. Usually recommend 'M' or 'Q' level.
- Download Format
- PNG/JPEG: Suitable for web pages, documents and everyday scenarios. SVG: Vector format, suitable for printing, posters and professional design scenarios requiring infinite scaling.

❓ Frequently Asked Questions
What is error correction level? Which one should I choose?
Error correction level determines the QR code's ability to be correctly scanned even when partially obscured or damaged. L level (7%) is suitable for clear environments, M level (15%) is recommended for daily use, Q level (25%) is suitable for printing applications, H level (30%) provides maximum error correction capability. Usually recommended to choose M or Q level.
What's the difference between PNG, JPEG, and SVG formats?
PNG and JPEG are bitmap formats, suitable for web pages, documents, and other daily scenarios. SVG is a vector format that can be infinitely enlarged without losing quality, suitable for printing, posters, and other professional design scenarios. If you need to print large-size QR codes, it's recommended to choose SVG format.
Can I embed a logo in the QR code?
Yes! You can upload a logo image (recommended to use square images), and the tool will automatically embed the logo in the center of the QR code. Note: The logo should not be too large (recommended not to exceed 20% of the QR code), otherwise it may affect scanning recognition. Also, SVG format does not support embedding bitmap logos.
Can the generated QR code track scanning data?
No. We generate static QR codes with fixed content and cannot track scanning times, locations, and other data. If you need tracking functionality, you need to use dynamic QR code services (usually paid services).
Can WeChat Scan recognize all types of QR codes?
No. WeChat [Scan] has limited support for standard QR codes. URL type can be perfectly compatible, but text, WiFi, email, vCard, and other types may not be recognized by WeChat or may not invoke corresponding functions. For the best experience, it's recommended to use the phone's built-in camera for scanning.
💡 Best Practice Recommendations
- 💡URL Sharing: Use URL shortening services to reduce QR code complexity and improve scanning success rate
- 💡WiFi Connection: Error correction level recommended to choose Q or H level, as QR codes may be printed and posted on walls, prone to wear
- 💡Printing Use: Choose SVG format output to ensure clarity after enlargement. Foreground and background colors should have high contrast (such as black and white)
- 💡Test Verification: After generation, be sure to test with multiple devices (iPhone, Android, different scanning apps) to ensure normal recognition
