JXL
JPEG XL目前技術上最出色的格式：壓縮效果優於 AVIF、支援漸進式解碼，還能對既有的 JPEG 照片進行無損重新壓縮，在畫質完全不變的情況下縮小約 20%。但瀏覽器的支援進展緩慢，且涉及不少角力。

GIF
Graphics Interchange Format每格畫面最多只有 256 色，技術上早已過時十多年，卻因為能在任何地方自動播放動畫而歷久不衰。若動畫長度超過幾秒，MP4 或 WebP 能以十分之一的體積呈現更好的畫質。

- GIF 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.
關於 JXL 轉 GIF 的常見問題
這個 JXL 轉 GIF 轉換器是免費的嗎？
是的。在這裡把 JXL 轉換為 GIF 完全免費，不需要帳號、沒有浮水印，也沒有每日次數限制。處理在你自己的裝置上完成，因此沒有需要轉嫁給你的伺服器成本。
我的 JXL 檔案會被上傳到任何地方嗎？
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 轉 GIF 有檔案大小限制嗎？
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 轉換為 GIF 會損失品質嗎？
No. GIF stores its data losslessly, so everything in your JXL file is preserved exactly.
可以一次把多個 JXL 檔案轉換為 GIF 嗎？
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 轉 GIF 能在手機、Mac 或 Chromebook 上使用嗎？
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.
