Watermark PDF on Mac

Search macOS for a PDF watermark feature and come back empty — Preview annotates single spots, never marks every page. The browser tool does: text or logo, all pages, from any Mac. Free with fair daily limits.

The gap in the Mac toolbox

Marking CONFIDENTIAL across a 30-page document is not a Preview job — its annotations are per-spot, per-page manual labor. Watermarking applies the mark document-wide in one setting, which is the entire point.

The Safari route

Upload, set the text or logo with opacity and position, download the marked copy — original untouched, mark on every page, no App Store detour.
