A PDF watermark is a semi-transparent text, logo, or image overlaid on your document's pages. Watermarking helps protect your intellectual property, indicate document status (like "DRAFT" or "CONFIDENTIAL"), or add branding to your PDFs. Unlike rotation which changes page orientation, watermarking adds a protective layer that doesn't alter your original content. All processing happens locally in your browser, so your files never leave your device — completely private and secure.
Whether you're sharing sensitive business documents, sending draft proposals, or distributing creative work, adding a watermark provides an extra layer of protection and professionalism. PDF watermarking lets you overlay text, logos, or custom graphics onto your document pages, making it clear who owns the content or what stage the document is in.
Lawyers watermark confidential documents before sharing with clients. Designers add proof watermarks to portfolios. Students mark draft thesis submissions. Businesses protect internal reports and proposals. Anyone sharing valuable PDFs can benefit from watermarking. Our tool makes it effortless — and because it works entirely in your browser, your sensitive documents never leave your computer.
