You give
One PDF file (up to 100 MB)
You get
The PDF with a semi-transparent text watermark on the chosen pages
Good to know
Works best with files under 100 MB (the upload cap); very large files depend on your device's memory. Text watermarks only (no image logos) using a built-in Latin font. The watermark is a separate layer that a determined person can remove with a PDF editor. Password-protected or permission-locked PDFs can't be edited: make an unlocked copy first (open it with the password and use Print → Save as PDF).

FAQ

Can someone remove the watermark?

With a full PDF editor, yes — it is a separate text layer. To make removal much harder, run the result through Compress PDF in Strong mode, which flattens each page into an image.

Will the watermark hide my content?

At the default 25% opacity the text underneath stays readable. Lower the opacity for a subtler mark.

Can I watermark only some pages?

Yes. Enter pages such as 1-3, 7 in the Pages box; leave it blank to stamp every page.
