Save your watermarked PDF
Add a watermark to PDF files online for free. Stamp confidential labels, draft notices, company logos, or custom text across every page before sharing reports, contracts, or internal documents.
Watermarks deter unauthorized reuse and make document status obvious at a glance — whether you are marking a proposal as DRAFT or branding client deliverables with your logo.
Upload your PDF, configure text or image watermark settings, preview the result, and download a watermarked file securely from your browser — no Adobe Acrobat required.
Why watermark PDFs online
Text and image watermarks
Apply custom text such as CONFIDENTIAL or INTERNAL USE ONLY, or overlay a logo watermark for brand consistency on every page.
Control opacity and placement
Adjust transparency so watermarks remain visible without blocking readability. Diagonal stamps are common for draft and review copies.
Protect before distribution
Watermark sensitive PDFs before email, portal upload, or print so recipients understand handling requirements.
Free browser-based tool
Add watermarks without installing desktop software or creating an account for core use.

watermark PDFs — frequently asked questions
Can I remove a watermark after adding it?
Watermarks become part of the exported PDF. Keep an unmarked original if you need a clean version later.
Will watermarking reduce PDF quality?
Text and logo watermarks overlay existing content. Body text and images stay at their original resolution.
Can I watermark only some pages?
The tool applies watermarks across the document. For selective pages, split the PDF first, watermark sections, then merge.
Is adding a watermark free?
Yes. Watermark PDF files for free on DSNOOPDOC with no signup required.
Are watermarked files stored on your servers?
Files are processed over HTTPS and removed after the task completes. Download your watermarked PDF immediately.
