Watermark PDF

What is Watermark PDF?

Watermark PDF is a free online tool that adds text or image watermarks to all pages of your PDF documents. Watermarks are semi-transparent marks that appear on each page, helping you protect your documents, indicate their status, or add branding.

When Would You Need to Watermark a PDF?

There are many practical reasons to add watermarks to your PDFs:

• Document protection: Add "CONFIDENTIAL" or "DO NOT COPY" to sensitive documents
• Draft indication: Mark documents as "DRAFT" or "FOR REVIEW" during approval processes
• Branding: Add your company logo to professional documents
• Ownership marking: Include your name or copyright notice on shared materials
• Sample marking: Mark preview documents as "SAMPLE" to prevent unauthorized use
• Legal compliance: Add required disclaimers or classification labels

Frequently Asked Questions

Can I watermark only specific pages?

Currently, watermarks are applied to all pages. For selective watermarking, you can split your PDF first, watermark the desired pages, then merge them back.

Will the watermark affect print quality?

No, watermarks are added at full quality. The opacity setting only affects visibility, not print resolution.

Can recipients remove the watermark?

Watermarks are embedded into the PDF content, making them difficult to remove without specialized software and editing skills.

What is the best opacity for watermarks?

For most uses, 20-40% opacity works well - visible enough to serve its purpose but not distracting from the content.

Is my PDF secure during processing?

Yes, your files are processed securely and deleted immediately after processing. We do not store or access your document content.
