Adding a watermark or stamp ensures your files are used correctly and your ownership is undeniably clear. Here is why stamping your PDFs matters.
Stamp your company's transparent logo across client proposals, whitepapers, and pitch decks to ensure you get credited.
Overlay a prominent copyright notice or your name across creative assets, photography, and original research before releasing them.
Add large, clear 'DRAFT,' 'APPROVED,' or 'VOID' text stamps so your team always knows a document's exact status at a glance.
Clearly mark HR policies, proprietary blueprints, or financial files with a 'INTERNAL ONLY' or 'CONFIDENTIAL' watermark.
Watermark your thesis, unpublished research papers, or original course materials to safeguard your intellectual property.
Apply bold 'PAID,' 'COPY,' or 'OVERDUE' stamps directly onto client invoices and receipts to maintain clear accounting records.
FynePDF draws your watermark into each page's content, so it becomes part of the document rather than a comment or annotation that can be toggled off. It appears the same in every PDF reader, prints with the page, and stays in place when the file is shared.
Type a stamp and set its size, color and opacity, or upload a logo and set how transparent it sits over the page.
One watermark covers the whole document, so a hundred-page report is stamped as quickly as a single page.
A watermark makes ownership and status obvious. Use Protect PDF to control who can open the file.
