Add Watermark stamps a text or image mark onto every page of a PDF, the standard way to label documents as confidential, draft, or copyrighted, or to brand them with a logo. You choose the content, then fine-tune how it looks and where it sits.
Text watermarks include ready-made presets (CONFIDENTIAL, DRAFT, COPY) or your own wording; image watermarks let you drop in a logo, where a transparent PNG gives the cleanest result. Opacity controls how subtle or bold the mark is, rotation sets the angle, and five placement modes, including a page-filling tiled pattern, decide where it lands.
Everything runs locally, so your document is never uploaded. That keeps internal and confidential files private, and there's no ToolsMonk branding added to your output and no usage cap.
Because a watermark becomes part of the rendered page, always keep an original un-watermarked copy if you might need a clean version later. For strong anti-copy marking, the tiled mode at moderate opacity and a diagonal angle is the most effective combination.
