Guides for watermarking PDFs
How to add a text watermark to a PDF
- Open your PDF in the watermark tool and keep Text selected.
- Type the text, such as CONFIDENTIAL, and choose font, size and colour. Use B and I for bold and italic.
- Click a square in Position, or tick Mosaic to repeat it across the page.
- Click Add watermark. The file is named …-watermarked.pdf.
How to add a logo watermark
- Choose Image, then Choose an image. A PNG with a transparent background looks best.
- Set the image size as a percentage of the page width.
- Pick a position and transparency, then save.
How to make a watermark faint and diagonal
- Set Transparency to 50% or 70% so the text underneath stays readable.
- Set Rotation to 45° for the classic diagonal look.
How to put a watermark behind the text
- Set Layer to Behind content.
- The watermark is drawn first, so text and images sit on top of it.
- On scanned pages the whole page is one picture, so a watermark behind it won't show. Use Over content with transparency there.
How to watermark only some pages
- Set from page and to under Pages.
- For example, from 2 to 10 to leave the cover clean.
