About Watermark PDF
A watermark tells readers the status of a document at a glance and discourages casual reuse. Type your text, choose where it goes and how strongly it shows, and it is added to every page.
A diagonal mark across the page at 20–40% opacity is the classic look: visible on every page without getting in the way of the text. Text watermarks use Latin characters.
Common watermark text
| Text | Tells the reader |
|---|---|
| DRAFT | The document isn’t final |
| CONFIDENTIAL | It shouldn’t be shared further |
| COPY | This isn’t the original |
| Your company name | Who the document belongs to |
Placement and opacity
Diagonal at 20–40% is hard to miss and leaves text readable. Use top or bottom placement at a higher opacity for a quieter label on documents that will be read closely.

Questions
Can a watermark be removed?
A determined person with PDF editing software may be able to remove it. It discourages reuse rather than preventing it. To restrict opening, use Protect PDF.
Can I use a logo image?
Not at the moment. This tool adds text only.
Does it cover the text underneath?
Keep the opacity low, around 30%, and the original text stays easy to read.
