Sending out drafts, samples, or proofs that should never be reused without permission? Stamp a Confidential, Draft, or Sample watermark across every page, with control over color, opacity, and rotation.
Photographers protect client previews, designers protect spec deliverables, and lawyers mark drafts before final signatures.
The first 30 pages of your PDF render to canvas in your browser so you can see exactly how the watermark will look on every page. The watermark overlay updates in real time as you change text, color, opacity, rotation, or position, no need to download to verify the layout.
A clean 3×3 button grid sets the watermark anchor point in one click, top-left, top-center, top-right, center-left, center, center-right, bottom-left, bottom-center, or bottom-right. The same anchor logic is used for both the on-screen preview and the final browser PDF tool export, so what you see is what you get.
Set any text up to 80 characters. Pick a hex color from the picker or type one in. Drag the font size slider from 10-200 px, opacity from 5-100%, and rotation from -180° to +180°. The default classic CONFIDENTIAL look is just one button click, but every parameter is fully customizable for branded or legal stamps.
Your PDF never leaves your device. Both live preview and export run entirely in your browser. No file is sent to any server, no account is needed, and nothing is stored. The watermarked PDF is generated locally and saved directly to your device.
