How to add a watermark to a PDF
Mark a document as a draft, stamp it confidential, or add your own logo across the pages.
Open the watermark tool

Why pdf2kit
Stamp private documents on your own device
A watermark often goes on a draft contract or a confidential report, so the file should stay private. pdf2kit adds the mark on your own device, and nothing is uploaded. It is free, with no account and no extra watermark of its own.
FAQ
Watermarking PDFs: common questions
Can I use text or an image?
Both. Type a word or phrase like DRAFT or CONFIDENTIAL, or add an image such as your company logo.
Can I make it fainter or bolder?
Yes. A strength control sets how strong the watermark looks, from a light tint to a bold stamp.
Does it go on every page?
Yes, the watermark is placed across all the pages of the document.
Can I remove the watermark later?
The watermark is baked into the downloaded file, so keep your original if you might need a clean copy.
Are my files uploaded?
No. The watermark is added on your device. Your file is never sent to a server.
