About this tool: Add Watermark
Apply configurable watermark text with opacity, font size, rotation, position and page selection directly in the browser.
The workflow keeps the document task focused on the selected PDF pages or settings and produces a downloadable result when processing succeeds.
PDF Watermark is presented in the shared NexterHub tool layout so the working controls stay near the top while the method, example, limitations and related utilities remain available below the result.
How it works
PDF Watermark reads and modifies the selected document in the browser with PDF libraries loaded only on PDF workflows; the build does not send the document to a NexterHub upload endpoint.
Practical example
Open PDF Watermark, enter a valid sample input, run the tool, and compare the displayed result with the values you supplied before using it in a real workflow.
Important notes
Keep an original copy of important documents and review page order, quality and output size before using the new PDF.
Privacy & processing
In the current NexterHub build, primary PDF processing runs in the browser and is not sent to a NexterHub upload endpoint.
