WebP 转 AVIF:值得升级吗?
如果您已经拥有 WebP 图像,转换为 AVIF 可以在相同质量下额外节省 15–25% 的文件大小。对于每月服务数百万图像的网站而言,这一减幅相当可观。不过,AVIF 的支持率(93% 的浏览器)略低于 WebP(97%),因此在决定仅使用 AVIF 前,请评估受众的浏览器分布。
推荐做法:同时提供两种格式
与其完全替换 WebP,不如使用 HTML <picture>
生成 AVIF 输出需使用 Chrome 或 Firefox
Safari 能解码 AVIF 图像,但不支持通过 Canvas API 对 AVIF 进行编码。此工具需要 Chrome 85+ 或 Firefox 93+ 才能生成 AVIF 输出。如果您使用 Safari,转换将失败——请切换到 Chrome 或 Firefox。
常见问题
Typically 15–25% smaller at equivalent visual quality. For a website with 1,000 images averaging 100 KB each as WebP, converting to AVIF would save 15–25 MB of total image weight, which can meaningfully improve page load times.
Yes - converting between two lossy formats always introduces some additional quality loss. Using quality 80 for AVIF output minimizes this while achieving excellent compression. At quality 75+, the difference from the WebP source is imperceptible under normal viewing conditions.
No - keep your WebP files as fallbacks. Serve AVIF to compatible browsers and WebP to older browsers using the HTML
<picture> element. Your WebP files serve about 4–7% of users that can't display AVIF.Safari can display AVIF images but cannot encode them via the browser Canvas API. Use Chrome 85+ or Firefox 93+ to run this tool for AVIF output. If you're on Safari, convert to WebP instead - it still gives you 25% savings over JPEG and works in all modern browsers.
