Add Watermark is a free online tool that stamps a text or image watermark over the pages of a PDF, helping you mark documents as draft, confidential, or your own.
Why watermark a PDF
A watermark signals ownership and status without changing the underlying content. Stamping CONFIDENTIAL, DRAFT, or a company name across each page deters unauthorized reuse and makes the document's purpose clear at a glance. It is a quick, professional way to protect work you share.
Text or image watermarks
You can add a text watermark with your own wording or upload a logo image. Position, opacity, and rotation are adjustable so the mark is visible without hiding the text beneath it. The watermark is applied to every page in one pass.
사용 방법 워터마크 추가
- Open Add Watermark in your browser.
- Drop your PDF onto the upload area.
