HEVC 轉 DV轉換工具
A free HEVC to DV converter for High Efficiency Video Coding (H.265) files. Browser-based pairs here usually run in this tab, with no file upload.
把你的 HEVC 檔案拖曳到這裡
or 瀏覽你的裝置 · 貼上快捷鍵 Ctrl+V
Accepts .hevc, .h265, .265 files. You can queue several files; each is processed one after another on your own device.
你的檔案不會離開這台裝置——沒有上傳，也沒有伺服器可以刪除它們。
- 01
新增你的 HEVC 檔案
把檔案拖放到上方的方框，或點擊以瀏覽選取。檔案會直接從磁碟讀取——不會傳送到任何地方。
- 02
檢查設定
DV is already selected. Open the gear icon on any row if you want to change quality, dimensions or codec before converting.
- 03
下載你的 DV
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。
HEVC
High Efficiency Video Coding (H.265)H.264 的後繼格式，能以大約一半的位元速率達到相近的畫質。解碼跟其他格式一樣在本機完成；編碼目前尚未接上瀏覽器內建選項，因此需要透過選用的伺服器端 worker 處理。

DV
Digital VideoMiniDV 攝影機使用的畫格內編碼格式，以固定的 25 Mbit/s 獨立記錄每一格畫面。非常適合剪輯，但對儲存空間來說相當浪費。

- Both HEVC and DV are lossy formats, so repeated conversions can accumulate rounding artifacts. Keep this to only what you need and avoid repeated round-trips.
關於 HEVC 轉 DV 的常見問題
這個 HEVC 轉 DV 轉換器是免費的嗎？
是的。在這裡把 HEVC 轉換為 DV 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 HEVC 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.
HEVC 轉 DV 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 HEVC 轉換為 DV 會損失品質嗎？
DV 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 HEVC file if you might need it again.
可以一次把多個 HEVC 檔案轉換為 DV 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.
HEVC 轉 DV 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.
