Watermark PDF
Put a watermark across every page of a PDF, either text or your own image: useful to make clear that a document is a draft or a copy, and to stamp quotes and invoices with your logo. You choose what gets stamped, where it goes and how visible it is.

How to do it, step by step
Upload your PDF
Drag in the document you want to stamp.
Choose text or image
A text like CONFIDENTIAL or DRAFT, or your own logo. The shorter the text, the bigger it looks.
Choose where it goes
The usual diagonal, repeated across the page, or at one specific spot: click the sheet-shaped grid.
Set colour and opacity
Between 20% and 30% the mark reads without getting in the way of the document.
Download the result
The mark lands on every page and the PDF stays an ordinary PDF.
