Watermarks should support the document, not fight it
A watermark is useful for drafts, confidential documents, ownership labels, and review copies. It should be visible enough to communicate status but light enough to keep the page readable.
Use short text, moderate opacity, and consistent placement. Long watermark text repeated across every page can reduce trust and make the document feel noisy.
Page numbers help reviewers cite exact locations
Page numbers are essential for contracts, reports, manuals, and multi-page submissions. They help reviewers reference a page without relying on PDF viewer numbering, which can differ from printed page labels.
Choose a position that does not cover footnotes, signatures, page headers, or existing page numbers. Bottom center and bottom right are common safe options.
Test one page before processing all pages
Before applying a watermark or numbering to a long PDF, preview a representative page. A cover page, a dense text page, and a page with tables may need different spacing.
If the document will be printed, check margins. Content close to the edge can be cut off by printers even when it looks fine on screen.
Practical checklist
- Use short watermark text such as Draft, Confidential, or Internal Use.
- Keep opacity low enough for body text to remain readable.
- Avoid covering signatures, tables, and existing headers.
- Use page numbers for long reports and review packets.
- Preview before exporting the full PDF.
