Add a watermark to a PDF offline

Watermarks discourage sharing and make the status of a document obvious. PDF Haven adds a real text watermark to every page (or only the pages you choose) and shows a live preview.

Step by step

1. Open the PDF and choose Watermark.
2. Type the text, pick size, colour and opacity.
3. Choose Diagonal or Horizontal, and Once, centred or Tiled across the page.
4. Optionally limit it to some pages (e.g. 2-5). The preview updates as you type.
5. Click Download with watermark.

Good watermark settings

• Draft for review: "DRAFT", tiled, 15–20% opacity — readable but impossible to miss.
• Confidential: red "CONFIDENTIAL", diagonal, 25%.
• Sharing a CV or portfolio: your name and the recipient's company, tiled at 10%.

Watermarks are added as page content, so they print. Remember that a determined person with editing software can still remove a watermark; for sensitive data use redaction.

FAQ

Can I watermark many PDFs at once?
