Common watermark text ideas

  • CONFIDENTIAL — for internal documents
  • DRAFT — for in-progress work
  • DO NOT COPY — for sensitive materials
  • Your company name — for branded documents
  • SAMPLE — for demo versions of proposals

Tips for effective watermarks

Set opacity to 20–35% for a subtle mark that doesn't obscure content. Use diagonal placement as it's harder to crop out. Large font sizes (60–80pt) work best for A4/Letter pages.

Frequently Asked Questions

How do I add a watermark to a PDF?
Upload your PDF, type your watermark text, adjust opacity and angle, and click Apply. The watermarked PDF downloads instantly.
Can I control where the watermark appears?
Yes. Set the angle (diagonal is classic), opacity (0–100%), font size, and whether it appears on every page or just specific ones.
Is the watermark permanent?
The watermark is embedded in the PDF content stream. It cannot be trivially removed by a reader, but advanced PDF editing tools can strip it.
