Protect sensitive PDFsText + logo watermarksApply to all pages
Stop sending unprotected PDFs that get copied and shared.
If you work with client deliverables, drafts, or internal documents, every unmarked PDF is a risk to your work and your brand.
Problem
Plain PDFs are easy to misuse
Contracts, proposals, and training material get forwarded, duplicated, and reused—often without credit or permission.
Agitation
Online tools are clunky and risky
Many “add watermark to PDF online” tools require uploads, show ads, and feel wrong for confidential files.
You waste time hopping between websites just to stamp one document.
Solution
Watermarks in Chrome, export in one click
Design a watermark once, preview it instantly, apply it to all or selected pages, and export—without leaving your browser workflow.
Who Watermark PDF is perfect for
Designed for individuals and small teams who need fast, consistent document protection in their everyday workflow.
Solo founders & consultants
Protect proposals, strategy decks, and reports before sharing them with prospects and stakeholders.
Agencies & freelancers
Stamp drafts, mockups, and previews with “Sample” or your logo so they are not reused without approval.
HR, legal & finance teams
Mark internal PDFs as “Confidential” or “Internal Use Only” to reduce accidental forwarding and leakage.
Features built for serious watermark workflows
Everything you need to design, preview, and apply professional watermarks—without complex PDF software.

All pages or selected pages
