Add a Text Watermark to Every Page of a PDF
A watermark stamps a word like Confidential, Draft, or Sample across your pages so the file cannot be reused or passed off as final. This tool adds that text to every page of a PDF at once, and you control exactly how it looks. Type the text, pick a color, and set the size, opacity, angle, and where it sits on the page.
The live preview shows every page with the watermark on it, so you see the result before you download, not after. A diagonal, half-transparent stamp in the center is the classic look, but you can move it to any of nine positions, turn it to any angle, and match your brand color. When it looks right, the watermark is written into a fresh PDF that opens in any reader.
Everything runs in your browser, whether you are here in India or anywhere else, so the PDF never leaves your device. That keeps contracts, invoices, and drafts private, with no server, no sign-up, and no watermark from us on the output.

Frequently Asked Questions
Common questions about adding watermarks to PDF files online.
How do I add a watermark to a PDF for free?
Upload your PDF, type the watermark text, and set the color, size, opacity, angle, and position. Click Download Watermarked PDF to save it. It is free, needs no sign-up, and runs in your browser.
Does the watermark go on every page?
Yes. The text you set is added to every page of the PDF in one pass, so you do not have to watermark pages one at a time.
Can I change the color and angle of the watermark?
Yes. You can set any text color, the font size, the opacity from faint to solid, and the angle from -180 to 180 degrees, plus one of nine positions on the page.
Will the watermark cover my content?
It sits on top of your pages at the opacity you choose, so a low opacity lets the text show through. The original content and layout of the PDF are never changed.
Is there a Pixellize watermark on the output?
No. The only text on your PDF is the watermark you type. There is no branding or extra mark added to the file.
Is my PDF safe when I watermark it?
Yes. The whole process runs inside your browser, so the PDF never leaves your device and is never uploaded to a server. Nothing is stored or shared.
