Add text or image watermarks to every page of your PDF. Mark documents as confidential, add your logo, or stamp draft status.
Before sending a proposal, report, or contract, adding a watermark communicates ownership and document status at a glance. A 'Confidential' stamp tells recipients how to handle the document. A company logo reinforces branding. A 'Draft' mark prevents confusion about document finality.
Watermarks are embedded directly into the PDF content — they appear on every page and cannot be removed without the original source file.
Protect your documents by adding text or image watermarks to all pages.

A PDF watermark is a visual element — text or image — overlaid on every page of the document. It's embedded into the PDF content layer, not just placed on top as an annotation. This means it appears when printed, viewed in any PDF reader, and cannot be removed by simply selecting and deleting it. Watermarks serve as ownership markers, status indicators, or branding elements.
Use cases include:
Marking a proposal as 'Confidential' before sending to a client.
Adding a company logo watermark to branded documents.
Stamping 'Draft' on documents that are not yet finalized.
Adding 'For Review Only' to documents sent for feedback.
Marking sample documents with 'Sample' to prevent unauthorized use.
Adding copyright notice to published PDFs.
Watermarked PDFs communicate ownership and document status clearly to all recipients.

The output PDF has the watermark permanently embedded in the page content.
PDF watermarks are added as content stream elements, not as annotations.
For text watermarks: the text is rendered as a PDF content stream element using the specified font, size, color, and opacity. It's drawn on each page's content layer at the specified position and rotation.
For image watermarks: the image is embedded as an XObject resource in the PDF. Each page's content stream includes a reference to this XObject, positioned and scaled as specified, with the opacity applied via the graphics state.
The watermark is part of the page content — not a separate layer that can be toggled off. This is what makes it permanent and visible in all viewing contexts.

You can add text watermarks (like 'Confidential', 'Draft', your company name, or any custom text) or image watermarks (like a company logo or signature). Both can be positioned, resized, and made transparent.
Yes. Transparency (opacity) is adjustable — from a very faint watermark that doesn't distract from the content to a bold, prominent mark. Most professional use cases use 20-40% opacity for a subtle but visible watermark.
Yes. The watermark is applied to all pages of the PDF. If you need different watermarks on different pages, you'd need to split the document, watermark each section separately, then merge them back.
A properly embedded watermark becomes part of the PDF content and cannot be removed by standard tools. This is intentional — the watermark is meant to be permanent. Keep the original unwatermarked version if you need it.
A diagonal text watermark saying 'CONFIDENTIAL' in a semi-transparent red or grey, positioned across the center of each page. This is clearly visible without completely obscuring the content.
Text watermarks add minimal file size. Image watermarks (especially logos) add the image data to each page, which can increase file size. If size is a concern, use a compressed PNG logo or a text watermark instead.
