Add Watermark to PDF
Stamp CONFIDENTIAL, DRAFT or your name across the pages of a PDF.
Type your text, pick diagonal, center or bottom and how strong it should be, then save. The watermark goes on every page, or only on the pages you list.
It works with any language and script, including accents, Cyrillic, Arabic, Chinese and Japanese, because the text is drawn as an image layer on top of the page. The original text of the PDF stays selectable.
Your PDFs are processed inside your browser with pdf-lib and pdf.js. Nothing is uploaded, nothing is stored, so it is safe for contracts, invoices, IDs and anything private.
How it works
- Drop your files Or tap to choose them. Several at once where it makes sense.
- Pick the options Pages, order, size or format, depending on the tool.
- Save Click the button, then save the new file.
FAQ
Can I remove the watermark later?
Keep your original file. The watermark is added on top of each page; there is no button to take it off again.
Does the PDF lose quality?
No. The pages are not re-rendered, only the watermark is added.
Is my document uploaded?
No. Everything happens in your browser, so contracts and IDs stay on your device.
Are my PDFs uploaded?
No. Everything happens on your device; the files never reach our server.
Is there a limit?
No page or file limit from us. Very large PDFs need enough free memory on your device.
Can it open password protected PDFs?
No. Remove the password in your PDF viewer first, then use the tool.
Is it free?
Yes. No account, no watermark, no daily limit.
