Watermark PDF Online — Complete Guide

Protect drafts and brand official documents with text or image watermarks. PdfPeaks applies semi-transparent overlays across PDF pages so recipients can see confidentiality labels, company names, or copyright notices without editing the underlying content.

How It Works

Upload the PDF, enter watermark text or upload a logo image, adjust opacity and placement, and apply. Download the watermarked PDF for client review, internal circulation, or social sharing when you want deterrence against unauthorized reuse.

  • Step 1 — Upload: Add the PDF to watermark.
  • Step 2 — Customize: Set text, opacity, rotation, or image stamp.
  • Step 3 — Download: Save the branded or confidential-marked file.

Security & Privacy

We treat uploaded files as sensitive data. When you use the PDF watermark tool on PdfPeaks, files are transferred over encrypted HTTPS/TLS connections and processed on secure servers in isolated temporary storage. They are used only to perform the operation you requested. Uploaded files and outputs are not permanently stored, are not used to train machine-learning models, and are never sold or shared with third parties for marketing. Temporary files are automatically removed after processing. For full details, see our Privacy Policy and Terms of Service.

Common Use Cases

Professionals, students, and everyday users rely on this tool for tasks such as:

  • Agencies: Mark concept PDFs as DRAFT before approval.
  • Legal: Label privileged copies for internal eyes only.
  • Photography: Preview portfolios with copyright text.
  • Finance: Stamp preliminary statements as unofficial.
  • HR: Distribute policy drafts with department watermarks.

Tips for Best Results

Watermarks deter casual copying but are not encryption — use Protect PDF for password security. Supported format: PDF (.pdf).
