Set one review mark for every page in the batch

Enter the exact diagonal label, tune opacity, and apply the same visible review status across several PDFs in one run.

Review the finished CLIENT REVIEW stamp across the real page, then move through the page deck to confirm the complete marked document.

Deliver marked copies while preserving selectable text

Review each separately named watermarked result; Foldout adds vector text across every page and keeps the source PDF unchanged.

Why it belongs

Why Watermark earns a place in the toolbox.

The practical details that make this job faster, clearer, or safer than doing it by hand.

One mark covers the full document

The centered diagonal placement is designed for review status and ownership labels that should not disappear into a corner.

Opacity remains deliberate

Choose how strongly the label should compete with the document before processing the batch.

Text remains useful

The watermark is added as vector text rather than flattening the complete source page into an image.

Clean sources stay available

Each marked result receives a separate -watermarked name and the original PDF remains unchanged.
