When to use Watermark PDF

Marking a draft with DRAFT before distributing, branding a portfolio PDF, or adding a CONFIDENTIAL stamp before sharing internally.

Key features

  • Any Text, Any Language — Company name, DRAFT, CONFIDENTIAL — in English, Urdu or any language.
  • Diagonal or Horizontal — Place the watermark across the page diagonally or straight.
  • Adjustable Opacity — Control how visible or subtle the watermark is.
  • Colour and Pages — Pick a colour and choose every page or only some.
  • Permanent Embedding — The watermark is burned into the PDF, not just a display layer.

Frequently asked questions

Can I change the colour and transparency?

Yes — choose grey, black, red, blue or green, and set the opacity from 5% to 100%.

Can I use Urdu, Arabic or other languages?

Yes. Text in any language is drawn using your device's fonts.

Can I leave the cover page without a watermark?

Yes — type the pages that should get it in the "Pages" box, for example 2-20. Leave the box empty to stamp every page.

Does a watermark stop copying?

It discourages it, but it doesn't technically prevent it. Combine it with Protect PDF to restrict copying.

Can the watermark be removed later?

It is drawn into the page content, so it can't simply be switched off in a PDF reader. Someone with editing software may still remove it, so keep your clean original private.
