Add a Text Watermark to Every Page of a PDF
A watermark shows ownership or status – "Confidential", "Copy", "Paid" or your brand name. The watermark tool stamps your text on every page.

Open the toolCustomise the watermark
- Text, size and colour.
- Opacity from very light to solid.
- Angle: 45°, 0°, -45° or 90°.
- Layout: one centred watermark or tiled across the page.
Ideas for sellers
- Mark catalog PDFs and price lists with your brand to discourage copying.
- Stamp "SAMPLE" on line sheets sent to new buyers.
- Mark internal documents "CONFIDENTIAL" before sharing.
Tiled or centred?
A single centred watermark looks clean on documents. A tiled layout repeats the text across the page, which is harder to crop out of screenshots of catalogs and price lists.

Tips
