Watermark a PDF without changing the rest

The watermark is placed on top of each page as a new layer. Your original text, links and images aren't touched, so the text stays selectable and searchable.

Everything happens in your browser. The PDF isn't uploaded, which matters for contracts, invoices and other private documents.

Mark documents that aren't final yet.

How to add a watermark to a PDF

Choose the PDF

Up to 100MB. It opens on your device.
Design the watermark

Type text or upload a logo, then set size, opacity, angle and position. The preview shows the first page.
Download

Every page gets the watermark, and you save the new PDF.

Good to know

Large diagonal text at 15–25% opacity is the classic DRAFT look and keeps the page readable.
The original text stays selectable, so the watermark can be removed by someone with a PDF editor. Don't rely on it as security.
Password-protected PDFs can't be opened. Remove the password in your PDF app first.
Need to take a watermark off a PDF you own? Use the PDF Watermark Remover.
