加浮水印

在每一頁加上文字或圖片浮水印。

Stamp text or an image across every page of your PDF. Adjust opacity, rotation, and position — ideal for marking drafts, adding confidentiality notices, or branding documents.

常見問題

Can I use an image as a watermark?

Yes. You can choose either text or an image as your watermark. Images can be positioned, rotated, and have their opacity adjusted just like text watermarks.

Will the watermark appear on every page?

Yes. By default, the watermark is applied to all pages in the PDF. Centre, diagonal, top, or bottom placement is available.

Can I make the watermark semi-transparent?

Yes. Use the opacity slider to make the watermark more or less visible. A lower opacity keeps the watermark subtle so it does not obscure the document content.
