Free PDF Watermark Tool — No Upload, Fully Private
Add 'CONFIDENTIAL', 'DRAFT', or any custom text as a diagonal watermark to every page of your PDF. Control opacity, color, and rotation angle. No file upload required.
What is PDF Watermark?
The Pix2Doc PDF Watermark tool adds customizable text overlays to every page of a PDF document — processed entirely in your browser using pdf-lib. You control the watermark text, font size, color, opacity, rotation angle, and position. This is the fastest way to brand a document as 'CONFIDENTIAL', 'DRAFT', or add your company name as a diagonal overlay no signup required. Because processing is local, even sensitive business documents like NDAs, contracts, or financial statements can be watermarked safely without being uploaded to any server.
Common Use Cases
- Adding 'CONFIDENTIAL' diagonally to a contract before emailing it to a client
- Stamping 'DRAFT' on a report to prevent it being used as a final version
- Adding a company name or logo text as a brand watermark on shared documents
- Marking a portfolio PDF with 'SAMPLE — Not for Distribution'
