PDF Watermark

Inserts a text or image watermark into a PDF file, or removes named watermark layers from it.

Purpose

Use this task to apply or remove watermarks from PDF documents as part of a document processing workflow. Text watermarks support configurable content, color, font, angle, and page targeting. Image watermarks support scaling and positioning. The Delete mode removes one or more named layers from the file, which is useful for stripping draft markings from approved documents.
