How to add a watermark to a PDF

Do you want to mark a PDF as draft, confidential, or as yours? Add a text watermark. PDFrust does this in your browser, directly across all pages.

Why use a watermark?

Watermarks indicate that a document is not yet final (Draft), cannot be shared publicly (Confidential), or belongs to you. It is also useful for proof versions of documents or to indicate copyright.

How do you add a watermark to a PDF?

Upload your PDF, type the text you want as a watermark (for example 'DRAFT' or your company name), and download the file. The text appears diagonally and semi-transparently across each page.

Can I remove the watermark?

A watermark placed in the file is part of the page and is not easy to remove without specialised software. Always keep the original version without a watermark.

Does this work in all PDF readers?

Yes. The watermark is baked into the PDF file as text and is visible in all PDF readers, whether you use Adobe Acrobat, a browser, or a mobile app.
