About this tool
A watermark shows that a document is a draft, a copy or confidential. Type your text, choose the size, color and strength, and it is placed across the middle of every page. Nothing is uploaded, so your document stays private.
How to use it
- Choose a PDF.
- Type the watermark text and adjust size, direction, color and strength.
- Select Add watermark and download the stamped PDF.
When this is useful
- Mark a document as DRAFT while it is being reviewed.
- Stamp CONFIDENTIAL on private files.
- Label a copy with a name or company.
- Show that a sample is not the final version.
Tips for best results
- Keep the strength between 20 and 30 percent.
- Diagonal watermarks are harder to miss.
- Use capital letters for short labels.
- Check the result in your viewer, then send it.
Good to know
The watermark is text placed over the page content and supports English letters, numbers and common symbols. It is a label and not a security feature.
Questions and answers
How do I keep the page readable?
Lower the strength slider so the watermark is faint. Around 20 to 30 percent works well for most documents.
Can I use an image or logo as a watermark?
Not yet. Use Edit PDF to place an image on a page.
Which characters are supported?
English letters, numbers and common symbols.
Can the watermark be removed?
A determined person can remove it with PDF software, so treat it as a label and not as protection.
