Beautify and customize QR codes in your browser — add colors, logos and rounded modules.
💡 容错级别越高,二维码被遮挡/损坏时的可识别性越强(但模块更密)。
| 要点 | 建议 |
|---|---|
| 纠错级别 | 越高容错越强,H 可遮挡约 30% |
| 对比度 | 前景/背景须足够对比,浅色渐变可能扫不出 |
| 静默区 | 四周留白至少 4 个模块宽,避免被裁切 |
美化时优先提升纠错级别,再调整配色,确保主流扫码器可识别。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Error correction | decoration must stay within the correction budget; H allows 30% | ISO/IEC 18004 |
| Contrast | modules need strong contrast; inverted codes often fail | ISO/IEC 18004 |
| Finder protection | never occlude the three finder patterns or quiet zone | ISO/IEC 18004 |
