Watermark PDF Online

Add text watermarks with full control over placement and appearance

Stamp custom text watermarks on every page of your PDF — controlling font size, color, opacity, rotation, and tiling. Processed entirely in your browser.

Open Watermark Tool

Your PDF never leaves your browser. All watermarking happens locally on your device. Nothing is uploaded or stored.

How it works

Full Appearance Control
Set font size, color, opacity, and rotation angle. Choose from presets like CONFIDENTIAL or type custom text.
Tiled or Single Placement
Place a single centered watermark per page or tile it in a repeating grid with configurable density and spacing.
Combine with Redaction
Apply redaction zones and watermarks in a single operation. Redaction runs first, preserving content integrity.
