How to add a watermark to a PDF (free, no upload)
Stamp DRAFT, CONFIDENTIAL, your name or any text across every page of a PDF — with control over position, opacity and colour.
A watermark tells everyone how to treat a document at a glance: a faint DRAFT across a proposal, CONFIDENTIAL on a report, or your name across pages you're sharing for review. Adding one to a PDF takes moments.
Open the PDF
Drop your document into the Watermark PDF tool; the first page previews your stamp.
Type and style the text
Set the text, then its position, size, opacity, angle and colour. A diagonal, low-opacity stamp is the classic look.
Apply and download
Export to stamp every page. The original content underneath stays intact.
Centre, tiled or corner?
A single centred stamp at a 45° angle is the recognisable "draft" style. Tiled repeats the text across the whole page, which is harder to crop out — useful for documents you don't want reused. Top or bottom placement suits a subtle name or URL.
Does it change the document?
The watermark is drawn on top of each page; the underlying text and images are untouched and still selectable. It's added on your device, so the PDF is never uploaded.
