Add Watermark to PDF
Add a watermark to PDF documents — diagonal DRAFT, CONFIDENTIAL, COPY, or custom text and image watermarks applied across every page with full control over opacity, angle, and colour.
Why teams use Watermark PDF
Watermarks signal intent: DRAFT means do not act on it, CONFIDENTIAL means handle carefully, CLIENT COPY means do not redistribute. This tool stamps a text or image watermark across every page of your PDF, with control over font, size, colour, opacity (typically 15-30% so the document remains readable), rotation angle (45° diagonal is standard), and position (centred, tiled, or corner). Multiple watermarks can be combined in a single pass.
Image watermarks support transparent PNG (for firm logos) and JPG (for solid scanned signatures). Logo watermarks usually sit small and faint in a corner rather than across the page so the document still looks professional. The watermark is flattened into the page content so it cannot be removed by reopening the PDF in Acrobat and deleting an annotation layer — it becomes part of the page.
Used by solicitors marking drafts, accountants distributing client copies, design studios circulating proofs, training providers protecting course materials, and HR distributing internal-only documents. Files run over TLS, are deleted within an hour, and never logged.
