What this tool does

Add a text watermark to selected PDF pages. Label a draft or mark the intended handling of a reading copy with a visible message such as confidential or review copy.

What you can open
One PDF, watermark text and appearance settings.
What you will download
One PDF with the chosen watermark text.

How to use it

  1. Choose the pages that need the label.
  2. Enter watermark text and set size, color and opacity.
  3. Download the file and check that the watermark is visible without hiding essential details.

Options explained

Pages
Select physical page positions: all, a range such as 1-3, several choices such as 1, 4, last, or the final page with last.
Watermark text
Enter the new text or typed visual mark. It is added to the page rather than replacing the existing text objects.
Font size
Set the text size in PDF points and check its readability at normal viewing size.
Opacity, percent
Set how opaque the added mark appears. A transparent mark leaves underlying content visible.
Color
Choose the color of the added text or graphic. A color overlay is not a redaction.

Know the tradeoffs

  • A watermark is a visual label, not an access-control or copy-prevention mechanism.
  • Text beneath a watermark remains part of the document.

Questions about this tool

Will a watermark stop someone copying the file?

No. It does not prevent copying or replace access controls.

Can I watermark only selected pages?

Yes. Use the page selector rather than applying it to all pages.
