Screen Recorder — 常见问题

Is my recording uploaded anywhere?+

No. It's captured and saved as a local file entirely in your browser — nothing is sent to a server.

Can it record audio too?+

Yes — tick microphone audio, and tab/system audio if your browser and the thing you're sharing offer it (Chrome supports it for a tab; a full screen or window usually doesn't include system audio).

What format does it save as?+

WebM in most browsers (Chrome, Edge, Firefox), which plays natively in any modern browser and video app. Need MP4? Run it through the WebM to MP4 converter afterward.

Does this work on mobile?+

No — screen capture via getDisplayMedia is a desktop browser feature. Use Chrome, Edge or Firefox on a computer.

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。
