Watermarks and confidentiality
Draft labels, internal-only banners, and signature images often appear on sensitive PDFs. Stamping locally keeps the underlying document off a third-party server.
Page numbers and branding
Add consistent page numbers across a deck or stamp a logo on every page with opacity control so content stays readable.
