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。

- PCX stores the incoming samples as provided, so this step does not add generic quality loss. If the source JXL was already lossy, those earlier losses remain.
- JXL 支持透明背景，而 PCX 不支持，因此源文件中的任何透明内容都会在转换过程中被压平到一个纯色背景上。
关于 JXL 转 PCX 的常见问题
这个 JXL 转 PCX 转换器是免费的吗？
是的。在这里把 JXL 转换为 PCX 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 JXL 文件会被上传到任何地方吗？
For browser-based pairs, your file is read locally and converted by ffmpeg in this tab. No file payload is uploaded; you may still see analytics and engine downloads in network logs.
JXL 转 PCX 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 JXL 转换为 PCX 会损失质量吗？
No. PCX stores its data losslessly, so everything in your JXL file is preserved exactly.
可以一次把多个 JXL 文件转换为 PCX 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.
JXL 转 PCX 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.
