AVIF
AV1 Image File Format使用 AV1 编解码器编码的静态图像，也是当前效率最高的格式 —— 在同等质量下体积往往只有 JPEG 的一半，并支持 HDR 和广色域。代价是编码速度较慢。

关于 AVIF 转 QOI 的常见问题
这个 AVIF 转 QOI 转换器是免费的吗？
是的。在这里把 AVIF 转换为 QOI 完全免费，无需账号、没有水印、也没有每日次数限制。处理在你自己的设备上完成，因此不存在需要转嫁给你的服务器成本。
我的 AVIF 文件会被上传到任何地方吗？
For browser-based pairs, your file is read locally and converted by Squoosh in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.
AVIF 转 QOI 有文件大小限制吗？
There is no imposed upload cap when it runs in-browser, but each conversion still depends on your device and browser memory. Large videos are the first practical limit, then memory-heavy documents or images.
把 AVIF 转换为 QOI 会损失质量吗？
No. QOI stores its data losslessly, so everything in your AVIF file is preserved exactly.
可以一次把多个 AVIF 文件转换为 QOI 吗？
Yes. Drop in several files and each gets its own row; they are processed one after another on your device. You can download them one by one or as one ZIP.
AVIF 转 QOI 能在手机、Mac 或 Chromebook 上使用吗？
Most modern browsers on Windows, macOS, Linux, ChromeOS, Android and iOS work. Very large videos are often more reliable on desktop or a browser with more memory.
Why do some conversions take longer on first run?
The conversion engine has to download first. Small codec bundles are fast, while ffmpeg is commonly 12–30 MB; later conversions of similar type use the cached engine.
I converted a file and the output is blank or unusable. What should I check?
Start over with default settings, then change one option at a time (quality, bitrate, page size, or codec) to isolate what changed behavior. If it keeps failing, retry with a smaller file and confirm the source format matches the pair.
