Photo Filters — frequently asked questions

What does 100% mean?+

For brightness, contrast and saturation, 100% is unchanged; below darkens/flattens, above boosts. For grayscale/sepia/invert, 100% is full effect.

Does it change the file format?+

No — it keeps the input format.

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。
