Stamp a text watermark — like DRAFT or CONFIDENTIAL — across every page of a PDF, with adjustable opacity, size, and a diagonal option.
How it works
- Upload the PDF you want to protect.
- Enter your custom watermark text and adjust the opacity, font size, and diagonal orientation.
- Click "Add watermark" to permanently stamp the file and download it.
Frequently asked questions
Can the watermark be easily removed later?
No, it is drawn permanently into the core page content. Always keep a backup of your original clean file if you need it later.
What opacity setting should I use?
Around 10–20% opacity is usually visible enough for protection without obscuring the vital text underneath.
Can I use an image logo as a watermark?
This specific tool adds text watermarks. If you need to stamp an image, you can use our Image tools to create a layout first.
