常见错误与修复方法
| 现象 | 可能原因 | 修复方法 |
|---|---|---|
| The code does not scan. | Contrast, quiet margin, size, payload density, or distortion is unsuitable. | Use dark foreground on a light background, preserve the margin, and test the final size. |
| The scan opens the wrong location. | The original input contains a typo or stale URL. | Inspect and test the exact decoded payload before distribution. |
Scan the final medium
该工具的实际边界： Low contrast, insufficient quiet margin, excessive payload, physical distortion, or very small printing can prevent a scan. Test the final printed or displayed code.

关于QR Code Generator的常见问题
Is QR content uploaded?
No. The matrix, preview, PNG, and SVG are generated in the browser.
Does a static QR code expire?
No. The destination can still stop working if the encoded URL changes or becomes unavailable.
Which correction level is suitable?
M is suitable for ordinary clean prints; Q or H trades capacity for more damage recovery.
