3

Is my video uploaded?+

No. Frames are grabbed from the video in your browser by seeking and drawing to a canvas — the file never leaves your device.

What formats can I get?+

JPG (smaller) or PNG (lossless). All the frames come back together in a zip.

How many frames can I extract?+

As many as you like — one every N seconds, or a fixed count. Very large numbers just take longer, since each frame is a seek.

Are the frame times exact?+

They're as accurate as the browser's seeking allows — usually within a frame or two of the requested time.

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。
