按下轉換，等待該列完成即可。若轉換多個檔案，可以將它們一起打包成單一 ZIP 檔下載。

MPEG

MPEG-1 / MPEG-2 Program Stream

支撐 Video CD 與 DVD 的原始數位影片標準。與老舊硬體的相容性極佳，但以現代標準來看效率相當低——同樣的畫質往往換來很大的檔案。

WV

WavPack

一種開放的無損編碼格式，具備特殊的混合模式：可以把檔案拆成一個較小的有損部分，加上一個能完美還原的校正檔。

轉換前值得了解的事

MPEG is already lossy, and while WV can be saved either way, this conversion cannot restore discarded details. Saving it lossless here preserves what is already present instead of discarding more.
這次轉換只會保留音訊軌——畫面會被完全捨棄。

FAQ

關於 MPEG 轉 WV 的常見問題

這個 MPEG 轉 WV 轉換器是免費的嗎？

是的。在這裡把 MPEG 轉換為 WV 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 MPEG 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.

MPEG 轉 WV 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 MPEG 轉換為 WV 會損失品質嗎？

It depends on your selected settings and codec path. Many engines can write either lossy or lossless output for WV, so you can usually increase quality if this file is your final version.

可以一次把多個 MPEG 檔案轉換為 WV 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.

MPEG 轉 WV 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.
