When you share important PDFs like reports, invoices, ebooks or certificates, you need to protect them from copying and show ownership.

Watermark types explained

Text Watermark: Ideal for marking status like DRAFT, SAMPLE, CONFIDENTIAL or adding your name/company. You can make it large, light gray, diagonal across center so it protects but remains readable. Image Watermark: Best for branding – upload your company logo in PNG with transparent background so it looks professional on every page. Both support opacity control from 10% to 100%.

Why add watermark to PDF?

Watermark shows ownership and prevents unauthorized copying. For businesses, logo watermark builds brand identity. For legal and official documents, CONFIDENTIAL watermark warns readers about sensitivity. For drafts, DRAFT watermark prevents confusion with final version. It is a simple but effective way to protect your intellectual property when sharing PDFs online.

How to add watermark to PDF

  1. Upload your PDF file.
  2. Choose watermark type – Text or Image.
  3. For text: enter watermark text, choose font size, color, opacity and rotation.
  4. For image: upload PNG logo and set size, opacity and rotation.
  5. Select position – center, corners or custom placement with 9 options.
  6. Choose pages – apply to all pages or enter custom pages like 1-3, 5.
  7. Enter custom file name and click Add Watermark to download protected PDF.

What happens after watermarking?

A new PDF is created with your watermark embedded on selected pages. Text watermark becomes part of page content and image watermark is merged with original pages. Original PDF remains unchanged. Final PDF keeps original quality, fonts and images with added protection layer, ready to share.
