为什么要把 AVIF 转为 JPG？
AVIF 是最新的主流图片格式，基于 AV1 视频编码。它的压缩率远超 JPG——同样画质下体积常常只有一半——这也是 Chrome、Firefox 和 Safari 现在都在网页上用它的原因。但在浏览器之外，支持度很低：大多数修图软件、打印机、手机和上传表单都没听过 .avif。转为 JPG，图片在哪都能用。
如何将 AVIF 转为 JPG
1. 把 AVIF 图片拖到上方框内，或点击选择文件。
2. Press Convert to JPG. 浏览器原生解码 AVIF，并以 92% 质量重新编码。
3. Files download automatically — singles directly, batches as a ZIP.
Requires a modern browser (Chrome 85+, Firefox 93+, Safari 16.4+). Older browsers cannot decode AVIF at all.
常见问题
What is AVIF?
AVIF (AV Image File Format) is based on the royalty-free AV1 video codec. It is backed by Netflix, Google, Apple and others, and typically beats JPG by 30–50% on file size.
Which browsers support AVIF?
Chrome 85+, Firefox 93+, Safari 16.4+ and Edge 121+ can display and decode AVIF. If your browser is older, this tool cannot run — update first.
Will I lose quality?
Slightly. The AVIF original holds more detail per byte, but at 92% JPG quality the visible difference is minimal.
Are my images uploaded?
No. Decoding uses your browser's native AVIF support; nothing leaves your device.
Can I batch convert?
Yes — multiple files download as one ZIP.
