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

Files are encrypted in transit and deleted after processing — see our Privacy Policy for details.

Common Use Cases

  • 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

Yes. Switch to Image Watermark and upload a PNG or JPG. Transparent PNG works best so the page does not get a white box. Position, opacity, and tiling match the text controls.

No. Anyone can still open and copy the file. Use Protect PDF when the file must not open without a password.
