Watermark PDF
Stamp “Confidential”, “Draft” or any text across every page of your PDF.
Marking a document before it goes out — “Confidential”, “Draft”, “Do not distribute”, or a recipient’s name — prevents misunderstandings and discourages casual copying. This tool repeats the text of your choice as a subtle watermark across every page of your PDF: diagonal or horizontal orientation, adjustable opacity so the mark stays visible without hurting readability, and adjustable size. Processing happens entirely on your device; nothing is uploaded to any server, which is reassuring for files that are, precisely, confidential. The watermarked PDF downloads in one click — free, with no account and no usage limit.
How does it work?
- Drop your PDF, then type the watermark text.
- Pick the orientation (diagonal or horizontal), opacity and size.
- Click “Apply”: the watermarked PDF downloads immediately.
Frequently asked questions
Does the watermark appear on every page?
Yes, the text is repeated uniformly on each page of the document, with the same opacity, size and orientation settings.
What opacity should I use?
A low opacity (around 0.1) marks the document without disturbing the reading. Go up toward 0.3 for a highly visible stamp — for instance on a draft that must never be mistaken for the final version.
Are my documents uploaded to a server?
No. The watermark is added directly on your device — your sensitive documents never pass through any server.
Can the watermark be removed?
It becomes part of the page content, like an ink stamp: there is no one-click removal, but a determined user with the right tools can always edit a PDF. Think of it as a deterrent, not absolute protection.
