Watermark PDF
Stamp text or a logo across every page of a PDF. Control opacity, angle, size, colour and tiling. Runs 100% in your browser — no uploads, no watermark of ours.
Add a Watermark to Your PDF — Free and Offline
Mark a PDF as CONFIDENTIAL, DRAFT or COPY, or stamp it with your own logo, without sending the file anywhere. Type any text or drop in a PNG or JPG, then dial in the opacity, rotation angle, size and colour, and choose whether the stamp sits once in the middle of each page or tiles diagonally across the whole sheet. A live preview shows the result before you commit, and you can place the watermark on top of the content or behind it. 100% browser-based, completely private, free, and no branding of ours added.

Frequently Asked Questions
How do I add a watermark to a PDF?
Upload the PDF, type your text or pick an image, adjust opacity and angle, then click "Add watermark". The stamped file downloads right away.
Can I use my own logo?
Yes. Switch to Image mode and select a PNG or JPG. Transparent PNGs work best, and the size is set as a percentage of the page width so it looks the same on every page size.
Can the watermark go behind the text?
Yes, there is a "behind content" option. Note that placing it behind rebuilds each page, which drops links and form fields from the original — keep it on top if the PDF is an interactive form.
Will the watermark appear on every page?
Yes, it is applied to all pages, and you can tile it diagonally to cover each sheet more thoroughly.
Can a watermark be removed again?
Not by this tool. The stamp is drawn into the page content, so keep an unwatermarked copy of the original if you will need one.
Is my PDF uploaded anywhere?
No. Both the PDF and any logo you choose are processed entirely in your browser.
