WMV
Windows Media Video微軟在 Windows Media 時代推出的專屬格式。在 Windows 以外的平台上播放並不方便，因此實務上它更常是被轉換掉的來源格式，而非目標格式。

關於 WMV 轉 3GP 的常見問題
這個 WMV 轉 3GP 轉換器是免費的嗎？
是的。在這裡把 WMV 轉換為 3GP 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 WMV 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.
WMV 轉 3GP 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 WMV 轉換為 3GP 會損失品質嗎？
3GP is a lossy format, so some detail is discarded when it is encoded. At the default quality setting the change is often not visually obvious; keep your original WMV file if you might need it again.
可以一次把多個 WMV 檔案轉換為 3GP 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.
WMV 轉 3GP 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.
