GIF
Graphics Interchange Format每帧限制为 256 种颜色，技术上早已过时十年，却因为能自动播放动画而在各处长盛不衰。对超过几秒钟的内容来说，MP4 或 WebP 在体积只有它十分之一的情况下效果会更好。

JXL
JPEG XL这批格式中技术上最出色的一个：压缩效果优于 AVIF，支持渐进式解码，还能对现有 JPEG 照片进行无损重新压缩，在零质量损失的情况下缩小约 20% 的体积。浏览器的采纳进展一直缓慢，且充满争议。

- GIF is lossless, and JXL can be either. At typical quality settings this lands on lossy and trades size for some quality loss. Keep GIF as a source if you may need a higher-detail version later.
关于 GIF 转 JXL 的常见问题
这个 GIF 转 JXL 转换器是免费的吗？
是的。在这里把 GIF 转换为 JXL 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 GIF 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.
GIF 转 JXL 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 GIF 转换为 JXL 会损失质量吗？
It depends on your selected settings and codec path. Many engines can write either lossy or lossless output for JXL, so you can usually increase quality if this file is your final version.
可以一次把多个 GIF 文件转换为 JXL 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.
GIF 转 JXL 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.
