PDF Watermark Adder: a worked example

Draft contracts must go out stamped "CONFIDENTIAL – DRAFT" diagonally on every page.

Input

contract.pdf · text "CONFIDENTIAL – DRAFT" · 45° · 20% opacity
PDF Watermark Adder produces

Output

contract.pdf with the stamp on all pages, text still readable

A semi-transparent diagonal overlay marks status on every page without obscuring the content and is hard to remove cleanly. It applies document-wide in one pass rather than page by page.

What is PDF Watermark Adder?

Add a text or image watermark to every page of your PDF. Watermarks are commonly used to mark documents as drafts, confidential, or to brand them with a company logo.

How to use

  1. 1Upload the PDF you want to watermark.
  2. 2Choose between a text watermark or an image watermark.
  3. 3Adjust position, size, opacity, and rotation to your liking.
  4. 4Preview the result and download the watermarked PDF.

Key features

  • Text and image watermark options
  • Adjustable opacity, rotation, and positioning
  • Apply to all pages or a specific range
  • Foreground or background layer placement
  • Live preview before downloading

Common use cases

  • Draft documents

    Stamp "DRAFT" across pages to prevent premature distribution of unfinished work.

  • Confidentiality notices

    Add "CONFIDENTIAL" or "INTERNAL USE ONLY" to sensitive business documents.

  • Brand identity

    Place your company logo on reports, proposals, or whitepapers before sending them to clients.

How it works

You can customize the watermark text, font size, color, opacity, and rotation angle. Image watermarks support PNG and JPEG files. The watermark is placed on a configurable layer, behind the content or on top of it, depending on your preference.

Frequently asked questions

Can I remove a watermark after adding it?

The watermark is permanently embedded in the output file. Keep your original unwatermarked PDF if you might need a clean version later.

Will the watermark cover the text?

You control the opacity and layer placement. Setting the watermark to the background layer with low opacity keeps it visible without obscuring content.

What image formats are supported for watermarks?

PNG and JPEG images can be used as watermarks. PNG with transparency works best for clean results.
