How adding a watermark to a PDF works
A watermark is a piece of text or a logo stamped semi-transparently across a page, and it's one of the simplest ways to mark a document's status or origin without changing its actual content. This tool lets you type custom text — like "DRAFT", "CONFIDENTIAL", or a company name — or upload your own logo image, then place it exactly how you want using a live preview that updates as you adjust font size, color, opacity, rotation, and position. That preview isn't a rough visual stand-in — it's generated by applying the watermark to a copy of your actual page and rendering the result, so what you see is what you get, down to the exact spacing of a tiled pattern.
You can stamp a single large watermark diagonally across the page (the classic "CONFIDENTIAL" look), or repeat it as a smaller tiled pattern across the entire page, which is harder to crop out of a screenshot or photocopy. For logos, you can also pin the watermark to a specific corner or the center using a 3×3 position picker. If you only want certain pages marked, the page-range option covers that too, and the preview automatically shows the first page inside whatever range you've chosen — not always page one. Everything happens locally in your browser — your PDF and logo are never uploaded to a server.
Common use cases
- Marking draft or in-review documents before they're finalized
- Adding a "CONFIDENTIAL" or "DO NOT DISTRIBUTE" stamp before sharing sensitive files
- Branding proposals, reports, or portfolios with your company logo
- Protecting shared PDFs from being passed off as someone else's work
Looking to remove an existing watermark instead of adding one? Use the separate Remove Watermark tool — this page only handles adding a new one.

Upload your PDF, choose text or a logo image, adjust the opacity/rotation/position with the live preview, then export — no account or payment needed.
Yes — the preview isn't a mockup or a rough approximation of the style. It's generated by applying the watermark to a copy of your actual page and rendering that result, the same way the file you download will look, including the exact tiled-grid spacing if you use that layout.
Yes — switch to Logo/Image mode and upload a PNG (transparency is supported) or JPG. Adjust its size and pick a corner, center, or tiled placement.
By default yes, but you can choose "Page 1 only" or a custom range like "2-5" if you only want specific pages watermarked. The preview automatically shows the first page inside whatever range you've selected.
A single diagonal stamp is the classic "CONFIDENTIAL" look — one large mark you place using a 9-point position picker. Tiled repeats a smaller version of the same text or logo in a grid across the whole page, which is harder to crop or clone-stamp out of a screenshot or photocopy than a single mark.
Yes — this tool adds a new watermark. If you're trying to remove an existing watermark from a PDF instead, use the separate Remove Watermark tool.
No. The watermark is drawn onto your PDF entirely in your browser — nothing is sent to a server.
