PNG to JPG — frequently asked questions
What happens to transparency?+
JPG has no transparency, so transparent areas are filled with white before encoding.
How much smaller will the JPG be?+
For photos, often 3–10× smaller than the PNG. For flat graphics with few colours the saving is smaller.
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。
