Edit PDF — frequently asked questions

Can I edit the existing text in a PDF?+

Yes — the Edit Text tool lets you change words already in the document, within the limits of the original fonts. To lay new text on top, use Add Text.

Is there one tool that does everything?+

PDF editing is split into focused tools so each one stays simple. This page points you to the right one for the change you need.

Do I need an account to edit a PDF?+

No. Every editing tool works immediately in your browser, with no sign-up and nothing uploaded.

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。
