Green Screen Remover — 常见问题

Is my video uploaded?+

No. The screen is keyed out and the new background composited entirely in your browser.

Does it need a real green screen?+

It works best with an evenly lit, solid, uncrinkled green or blue backdrop and no matching color in the subject's clothes or skin tone — the same conditions any chroma key tool needs.

Can I use my own background image instead of a color?+

Yes — switch to Image and upload one; it's scaled to fill the frame behind the keyed subject.

Which browsers work?+

Chrome, Edge and Safari 17+ — keying 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。
