Resize Video with Blurred Background — 常見問題

Is my video uploaded?+

No. It's resized entirely in your browser.

How is this different from Crop Video?+

Crop cuts off whatever doesn't fit the new shape. This keeps the entire original frame visible, centered over a blurred, scaled-up copy of itself filling the rest — nothing is cut off.

Which shapes are supported?+

9:16 (TikTok, Reels, Shorts), 1:1 and 4:5 (Instagram), and 16:9 (YouTube).

Which browsers work?+

Chrome, Edge and Safari 17+ — the resize 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。
