Add a watermark to a PDF
Stamp CONFIDENTIAL, DRAFT, COPY or your name across every page.
How to use it
- Add your file. Drop it on the box above or tap it to pick it from your device.
- Choose and run. Type the text, then drop the PDF.
- Download. Press Download. Nothing was uploaded, so nothing is stored anywhere.
What it does
Your text is drawn large, diagonal and light grey across the middle of each page, so the content stays readable.
When to use it
Drafts, confidential documents, samples sent to clients, and copies of ID sent for verification.
Private by design
Most online tools upload your file to their servers. This one doesn't: it loads into your browser and does the work on your own phone or computer, so your files never leave it.
Questions
Is this watermark pdf free?
Yes, completely free, with no account, no watermark and no daily limit.
Are my files uploaded?
No. Everything happens inside your browser on your own device. Nothing is sent to us or anyone else.
Does it work on iPhone and Android?
Yes, in Safari, Chrome and other modern browsers.
Does it work with password-protected PDFs?
No. Remove the password with the app that made the PDF first; this tool can't open locked files.
