About this tool

Stamp a professional text watermark — DRAFT, CONFIDENTIAL, SAMPLE, your company name — onto every page (or a range) with full control: diagonal or horizontal, font size, opacity, gray or colored. Built on pdf-lib, everything happens locally; the watermarked file is written on your device. Honest note: this tool adds text watermarks. Image/logo watermarks (PNG stamping) are supported by our PDF editor's text flow only in text form today; a background-image watermark needs raster flattening, which this tool intentionally avoids to keep text crisp and file size small.

FAQ

Can I put my logo as a watermark?

This tool stamps text watermarks (fast, crisp, tiny file-size impact). For a logo watermark, images can be added via our PDF editor flow — full image-watermarking is on the roadmap.

Will the watermark appear on top of my text?

Yes, it is stamped over the content with adjustable opacity — 15–25% is the sweet spot so body text stays readable underneath.

Is my document uploaded anywhere?

No — watermarking happens in your browser with pdf-lib; nothing is sent to any server.

Can I watermark only some pages?

Yes — enter a range like 1-3 or 7,10-12 and only those pages get the stamp.

What angle should I use?

-45° (diagonal bottom-left to top-right) is the standard 'DRAFT' look. Set angle to 0 for a horizontal footer-style stamp.

Is the watermark removable?

Any visible watermark can theoretically be covered or removed with editors — watermarks deter, they don't encrypt. For real protection see honest guidance in our guides section.
