About This Tool

Add Watermark allows you to place text or image watermarks on your PDF documents. Watermarks can indicate document status (Draft, Confidential), add branding, or deter unauthorized copying.

Customize the watermark's position, size, opacity, rotation, and color. Apply to all pages or select specific pages. The tool supports both text watermarks and image watermarks.

All processing happens locally in your browser, ensuring your documents remain private.

Practical guide for this tool

Use Add Watermark when a PDF needs visible text or image branding such as Draft, Confidential, Approved, or a company mark.

What this tool does

  • Adds visible text or image watermarks to PDF pages for draft, confidential, approved, or branded copies.
  • Lets users adjust placement, opacity, and rotation so the watermark is visible without blocking the document.
  • Creates visible page content; it is not the same as password protection or access control.

When to use it

  • Stamping internal drafts, review copies, or confidential documents.
  • Adding company branding to PDFs before distribution.
  • Applying repeatable visible markings without leaving the browser.

Practical examples

  • Mark a review copy: start with proposal.pdf with Draft text watermark and check that the output matches proposal-draft.pdf.
  • Brand a report: start with report.pdf with company logo watermark and check that the output matches report-branded.pdf.

Privacy and file handling

  • Use this tool only on documents you own or have permission to process.
  • OpenToolsKit is designed around browser-side processing where applicable, but you should still inspect the downloaded result before sharing it.
  • Keep the original file until the output has been opened and verified.

Common mistakes to avoid

  • Using a watermark as a security feature when encryption or permissions are needed.
  • Placing dark watermarks over small text or form fields.
  • Forgetting to save an unwatermarked original for future edits.

Troubleshooting

  • If the watermark is too strong, reduce opacity or move it away from important text.
  • If you only need page numbering or headers, use those dedicated tools instead.

Limitations and edge cases

  • Watermarks are visible page content, not access control. Use Encrypt PDF or Change Permissions for security settings.
  • If you only need page numbers or headers, those dedicated tools are usually simpler than a watermark workflow.

Frequently Asked Questions

Can I use an image as a watermark?

Yes, you can upload PNG, JPG, or SVG images to use as watermarks.

Can I make the watermark semi-transparent?

Yes, you can adjust the opacity from fully transparent to fully opaque.

Can I apply different watermarks to different pages?

The tool applies the same watermark to selected pages. For different watermarks, process the document multiple times.

Does a watermark protect a PDF from copying?

No. A watermark is visible labeling. Use encryption, permissions, or a controlled sharing process when access control matters.

What should I check before sharing output from Add Watermark?

Open the downloaded file and verify page order, readability, visible edits, and any privacy-sensitive details before sending or filing it.

Does Add Watermark upload my document to OpenToolsKit servers?

OpenToolsKit is designed around browser-side processing where applicable. Some browser features, third-party links, or unsupported file types can have different boundaries, so review the privacy page for details.
