Protect Your Intellectual Property

Whether you're sharing an eBook, a portfolio, or a whitepaper, a visible watermark ensures your content can't be easily screenshotted and passed off as someone else's work.

Build Brand Recognition

Every document you send out is a marketing opportunity. A subtle logo watermark reinforces your brand identity with every page.

Mark Documents as Drafts or Confidential

Using a watermark makes document status unmistakable. For drafts, use a large, semi-transparent 'DRAFT' watermark across the center of each page.

Cost of Professional Software
