Remove Silence from Video — 常见问题
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.
你们会把我的文件上传到服务器吗？+
不会——这里的每个工具都完全在你的设备上处理文件，不会向服务器上传任何内容。唯一的例外是 AI 工具，它们会把提取的文本（而非文件本身）发送给 Claude 来完成工作。
有文件大小限制吗？+
我们没有人为设置限制，但由于处理过程在你的浏览器中进行，非常大的文件（超过 500MB 或 1000 页）会受到你设备内存的限制，而非我们的限制。
