What is Text Watermark?

Text watermarks mark a document's status โ€” DRAFT, CONFIDENTIAL, APPROVED โ€” or assert ownership. PDFStream adds a diagonal text watermark to every page of your PDF, entirely in your browser. Customize the text, opacity, color, and size. The watermark is applied as a semi-transparent overlay so the underlying content remains readable. Download the watermarked PDF ready to share. Use cases: marking draft documents before final review, labeling confidential documents before distribution to external parties, asserting copyright on shared content, or flagging sample documents sent to prospects.
