Why use our PDF watermark tool?
Watermarking is a practical way to assert ownership, indicate document status, or discourage unauthorized redistribution of your documents. Marking a draft report as 'DRAFT' prevents outdated versions from being mistaken for final copies. Stamping your company logo across client deliverables reinforces your brand on every page. Adding 'CONFIDENTIAL' to sensitive internal memos makes the access level immediately clear to anyone who opens the file. Our tool applies text or image watermarks to every page of your PDF with full control over placement, size, opacity, color, and rotation angle — all processed locally in your browser for maximum privacy. No software to install, no account to create, and the tool works on any device.
For stronger document security, combine watermarking with password protection to restrict who can open the file. You can also flatten the PDF afterward so the watermark becomes a permanent, unremovable part of the page content, or compress the result to keep the file size lean for email distribution. The tool is completely free with no limits on the number of pages.
