What is PDF Watermarking & Stamping?
PDF watermarking is the process of embedding semi-transparent text, logos, or status stamps onto document pages. It is commonly used to designate confidentiality, indicate review status (such as DRAFT or APPROVED), prevent unauthorized reproduction, and brand corporate files.
TurboPDF provides advanced client-side watermarking, allowing you to fine-tune text typography, colors, opacity, rotation angle, exact 9-point or grid positioning, and page selection without transmitting sensitive documents to external servers.

Pro Tips for Perfect PDF Watermarking
Optimal Opacity Settings
Keep text or logo opacity between 25% and 40% to maintain document readability while ensuring the watermark remains clearly visible.
Use Transparent PNGs for Logos
When applying image stamps, upload transparent PNG graphics so that the underlying document content remains legible without white background boxes.
Diagonal 45-Degree Text Stamping
A -45° or 45° angle provides maximum coverage across the diagonal of the page, preventing easy cropping of the watermark.
Selective Page Watermarking
Use the target page filter to apply watermarks exclusively to odd pages, even pages, or only the cover sheet as needed.
