当你需要干净的源文件、精确的像素，或与设计工具广泛兼容时，请使用 PNG。当你想要更小的网站传递文件且浏览器支持良好时，请使用 WebP。当你正在大幅优化、且能测试完整发布流程时，请考虑 AVIF。
快速决策表
| 需求 | 较好的起点 |
|---|---|
| 透明标志来源 | PNG |
| 网站截图传递 | WebP |
| 产品照片传递 | WebP 或 AVIF |
| 无损编辑 | PNG |
| 激进的页面加载量削减 | 测试后的 AVIF |
当你有大型 PNG 文件、又想要快速的传递副本时，请试试 PNG to WebP。
常见问题
WebP 总是比 PNG 好吗？
不一定。WebP 在传递时通常更小，但 PNG 在可编辑的源文件、微小图形，以及精确的无损工作流程上可能更好。
我该对每张图片都用 AVIF 吗？
AVIF 可以非常高效，但编码可能较慢，而且工作流程的支持程度不一。在把它当成唯一格式前请先测试。
