当您需要工具支持更广泛的格式，或需要更小、更适合浏览器的文件用于网站时，可将 AVIF 文件转换为 WebP。
一切都在您的浏览器中完成，因此您的图片保持私密。
如何使用此工具
添加 AVIF
将您的 AVIF 文件拖放到工具上，或从您的电脑中选择。
WebP 已默认选中
输出格式已经是 WebP。如有需要，可调整质量。
对比并下载
预览效果，然后下载您的 WebP。

Converting backwards, and why you sometimes need to
AVIF gives the smallest files, but WebP is the safer format in practice: it has broader support, especially on slightly older browsers and in older image editing tools, and it is accepted by more content management systems and upload forms.
Moving from AVIF to WebP means re-encoding an already-lossy image, so a little quality is lost. You also lose the size advantage — expect the WebP to be larger than the AVIF it came from, sometimes by 20–40%.
When this conversion is the right call
- A CMS or upload form rejects AVIF but accepts WebP — still a very common restriction.
- You need to edit the image, and your editor does not open AVIF.
- You are standardising a mixed library on one format, and WebP is the one with the fewest compatibility surprises.
When it is not
If the image is already live on a page and the browser support is fine, leave it as AVIF. Converting to WebP only makes the file bigger. Reach for this conversion when something downstream refuses AVIF, not as a general tidy-up.
常见问题
为什么要将 AVIF 转换为 WebP？
在较旧的浏览器以及许多尚不支持 AVIF 的工具和平台中，WebP 的支持范围更广。
WebP 的质量好吗？
是的 — 在合理的质量设置下，对于大多数图片，WebP 在视觉上与源图片几乎没有区别。
它私密吗？
是的。图片在本地处理，绝不会被上传。
