About Add Watermark to PDF
Add a watermark to a PDF online to mark drafts, protect shared copies or brand your documents. Choose a text watermark such as Confidential, Draft or Copy, or upload your logo as an image. You can set the size, colour, opacity and angle, and place it diagonally, tiled, in the centre or in a corner.
Apply the stamp to all pages or only the ones you choose, and check the live preview before you download. It is useful for sharing ID copies with a note such as "For bank KYC only". Your PDF is processed in your browser and never uploaded, and the tool is free with no sign-up.

Frequently asked questions
Are my files uploaded anywhere?
No. The file is opened and processed entirely inside your browser using JavaScript libraries. Nothing is sent to a server, so it is safe for confidential documents.
Can the watermark be removed later?
It is drawn into the page content, so it cannot be switched off like a layer. Someone with a PDF editor could still delete it, so it deters copying rather than preventing it.
Can I use Hindi text?
The built-in PDF fonts cover Latin characters only. For Hindi or other scripts, make an image of the text (PNG with transparent background) and use an image watermark.
What about password-protected PDFs?
Encrypted PDFs cannot be edited directly. Remove the password first with the Unlock PDF tool (you need the password), then use the unlocked copy.
How do I add a watermark to all pages of a PDF?
Create your text or image watermark, keep the page option on All pages, and click Add watermark. Every page gets the same stamp.
Can I add a logo as a watermark?
Yes. Choose the image option and upload your logo; a PNG with a transparent background looks cleanest. Lower the opacity so the page content stays readable.
