Add CONFIDENTIAL or DRAFT Watermark to PDF Free — Browser-Based
Stamp any text watermark on every page of a PDF directly in your browser. Nothing is uploaded. Choose opacity, text, and download instantly.
Sharing a draft without a watermark means the recipient might think it is final. Sharing a confidential document without a watermark leaves no visible indication of its sensitivity. Text watermarks communicate document status clearly and prevent accidental misuse.
What watermarks actually do
Watermarks are a deterrent and a communication tool, not a security mechanism. Anyone with Acrobat can remove a PDF watermark. But most document misuse is careless, not malicious. Someone forwards a draft before it is reviewed. Someone prints a SAMPLE and hands it over as real. Watermarks stop those accidents.
Adding a watermark in your browser
- Open the PDF Watermark tool.
- Upload your PDF and type the watermark text.
- Set opacity: 20-30% for professional documents, higher for demo prevention.
- Download the watermarked PDF.
Common watermark text choices
- DRAFT -- Until the document is approved.
- CONFIDENTIAL -- For sensitive business information.
- SAMPLE -- For demo content sent to prospects.
- DO NOT DISTRIBUTE -- For documents shared in a controlled context.
