Watermark PDF stamps a text label across every page — useful for drafts, internal copies, review versions or ownership notices. You can set the text, colour and opacity before creating the new file.
The watermark is rendered as an image in the browser so Persian, Arabic and emoji text can be shaped correctly. It is then embedded into each page without sending the PDF to a server.
How to use
Choose the PDF and enter the watermark text you want to display.
Adjust colour and opacity so the mark is visible without hiding the document.
Create and download the watermarked PDF, then inspect a light and a dark page.
FAQ
Is the watermark added to every page?
Yes. The same centred watermark is embedded on every page of the output PDF.
Can I use Persian or Arabic text?
Yes. The watermark text is rendered through the browser first, which allows right-to-left scripts and emoji to be drawn correctly.
Can a watermark be removed later?
A determined editor may be able to remove or cover a visual watermark. It is a visible notice, not cryptographic copy protection.
Is my PDF uploaded?
No. The watermark is created and embedded locally in your browser.
