About Watermark PDF
Watermark PDF stamps your own text across every page — DRAFT, CONFIDENTIAL, a company name — to discourage misuse and make a document's status unmistakable.
How to use Watermark PDF
Add your PDF file
Drag your PDF file onto the upload area at the top of the page, or tap it to browse your device. You can also pick a file straight from a phone or tablet — the interface adapts to small screens.
Type your watermark text
Enter the wording you want repeated on each page. Short phrases in capitals read best at an angle.
Apply to the whole document
The text is drawn semi-transparently across every page so the underlying content stays readable beneath it.
Download your watermarked PDF
A result card appears directly under the upload box. Press the download button and the watermarked PDF is saved to your device immediately. The upload area stays open, so you can process another file without reloading the page.
Key features & benefits
Every page covered
No page is missed, including pages added later in the document.
Readable, not ruined
The stamp is translucent, so reviewers can still read the content it protects.
Custom wording
Use any text you like — a status label, a client name or a date.
Baked into the file
The watermark becomes part of the page content rather than a removable annotation layer.
