Why people watermark PDF documents

For files that go to clients, partners, or your team

Drafts in review
Mark every page as a draft, so no one signs or forwards an unfinished version.
Confidential files
Mark every page as confidential, so contracts, reports, and HR files stay labeled wherever they go.
Branded documents
Add your logo to every page, so proposals and price lists carry your brand.
Your own work
Add your name with a © symbol, so it’s clear who the work belongs to.

Set what your PDF watermark says and where it goes

Everything is set in one panel, next to a preview of your document

Text or an image

Type any text, like “Confidential” or your company name, or upload an image and crop it.

Font, color, and angle

Pick a font and a color, then set the size, opacity, and angle. Add the date if you need it.

Once or across the page

Put it in the center or a corner, or repeat it in a grid or offset grid with your own spacing.
