About the Watermark PDF

A visible watermark such as CONFIDENTIAL, DRAFT or your company name discourages copying and makes the status of a document clear. Choose the text, size, colour, transparency and angle, and stamp it across every page.

When to use it

  • Marking drafts so they are not mistaken for final versions
  • Labelling confidential reports and quotations
  • Branding sample documents shared with clients
  • Adding “COPY” to scanned certificates

Tips for the best results

  • Opacity around 20–30% keeps the document readable
  • A diagonal watermark is harder to crop out
  • Keep the original unwatermarked file for your own records
