About Add Watermark

Add Watermark stamps text or an image across every page of your PDF — useful for marking documents as Draft, Confidential, or branding them with your company logo. It is a complete answer to how to add watermark to PDF free without paying for Adobe Acrobat. Choose your text, font, opacity, position, and rotation, or upload a logo file to add image logo watermark to PDF pages. The watermark is baked into the PDF permanently, so it appears in every reader on every device — exactly what you need when you have to stamp confidential watermark on PDF online before sharing a sensitive draft externally. People use this tool to add text watermark to PDF without Acrobat for legal documents, to brand client deliverables before sending them, or simply to watermark PDF document online without software when they don't have access to a desktop tool. Everything happens locally in your browser, so even sensitive contracts and financial statements stay on your device. The result is a clean, professional-looking PDF that signals at a glance who owns the content and what its status is.

Common use cases for Add Watermark

  • Stamp DRAFT across every page of a proposal you are circulating internally for review.

Tips & best practices for Add Watermark

  • Set opacity to around 20–35% so the watermark is visible but does not interfere with reading the underlying content.
  • Diagonal watermarks across the centre of the page are the hardest to remove or crop out.
  • Use a logo PNG with a transparent background so the watermark blends naturally into the page.
  • Pick a font size that scales with the page — too small disappears on large pages, too big distracts from the content.
  • Add the watermark after merging or splitting pages, never before — that way every final page is stamped consistently.
  • Test the watermark on one page first by extracting it, applying the watermark, and previewing the result.
