Watermark PDF

A watermark is a semi-transparent label placed on every page of a PDF, usually text such as DRAFT, CONFIDENTIAL, or SAMPLE, or a faint company logo. It signals the status or ownership of a document at a glance, without anyone needing to read a cover note first. Law firms watermark draft contracts so nobody mistakes them for the signed final version. Design agencies watermark proofs before a client has paid, so the images cannot be used commercially yet. Photographers watermark previews before a client selects and pays for full-resolution copies, and real estate agents put a small logo watermark on floor plan PDFs shared with prospective buyers. Because the watermark sits on top of the existing page content, the underlying document is unchanged underneath it.

Lawyers marking drafts, designers sharing proofs, HR teams labeling internal documents, and small businesses putting a logo on client-facing PDFs before final approval.
