Can I watermark only specific pages?

Currently all pages. To watermark a subset, split, watermark the subset, then merge back.

Is the watermark editable later?

It is baked into the page content, like any printed text. To remove, you'd need the original or a careful redact.

Does it work for scanned PDFs?

Yes, the watermark draws on top of the rendered page regardless of content.

Why is my watermark too dark/light?

Adjust opacity. 0.3 (30%) is a typical diagonal stamp value.

Can I rotate the watermark?

Default is 45° diagonal. Custom rotation is on the roadmap.

Add watermark

pdfty's watermark tool adds a text watermark — like CONFIDENTIAL, DRAFT, your name, or a date — to every page of a PDF. Adjust opacity, font size, and position. The result is one PDF with the watermark baked in.

Useful for sharing draft documents that should not be circulated as final, for marking proofs, or for branding internal copies. Diagonal watermarks are common for visibility while staying out of the way of the main text.

Built with PyMuPDF for precise positioning. Works on any number of pages. Pages keep their original size and quality.
