Remove Silence from Video — 常見問題
Is my video uploaded?+
No. The audio is analyzed and the cuts are made entirely in your browser.
How does it detect silence?+
It measures the audio's loudness in short windows and marks the stretches that stay below the sensitivity threshold for long enough as silence — a little padding is kept around each cut so it doesn't feel abrupt.
Will it cut off words?+
It's tuned to be conservative by default — Low sensitivity only cuts long, obvious silences. High is more aggressive and can occasionally clip a soft word start; preview the result before trusting it on important footage.
Which browsers work?+
Chrome, Edge and Safari 17+ — cutting the video needs WebCodecs.
你們會把我的檔案上傳到伺服器嗎？+
不會——這裡的每個工具都完全在你的裝置上處理檔案，不會向伺服器上傳任何內容。唯一的例外是 AI 工具，它們會把擷取的文字（而非檔案本身）傳送給 Claude 來完成工作。
有檔案大小限制嗎？+
我們沒有人為設下限制，但由於處理過程在你的瀏覽器中進行，非常大的檔案（超過 500MB 或 1000 頁）會受你裝置記憶體的限制，而非我們的限制。
