Add a watermark to a PDF
A watermark prevents misunderstandings: it makes clear that the document is a draft, a copy or internal material, on every single page.
- Free, no watermarks
- Works offline
- Your file stays on the phone
How it works
- Open NAPDF and tap "Watermark".
- Pick the PDF and type the text you want stamped.
- Set how transparent it should be and save: the text appears on every page.
What people use it for
- Mark a quote as DRAFT.
- Identify copies of an original document.
- Flag material meant for internal use only.
Lay a diagonal text over every page, such as "DRAFT" or "COPY", as faint or as strong as you like.
