Watermarking your documents and images is one of the most effective ways to protect your work, establish ownership, and prevent unauthorized use. Whether you're a photographer, business owner, or just want to mark confidential documents — this guide shows you exactly how to do it for free.
Why Add Watermarks to Your PDF Documents?
- Prove ownership: Clearly mark documents as yours with your name or company
- Protect confidential info: Mark sensitive documents as CONFIDENTIAL or DRAFT
- Prevent unauthorized copying: Visible watermarks discourage plagiarism
- Professional branding: Add your business name or website to all documents
- Document status: Mark documents as APPROVED, REJECTED, or SAMPLE
- Legal protection: Watermarks serve as evidence of ownership in disputes

💡 Pro Tip: Font Size Matters
Use a font size between 36-60 for a visible but not overwhelming watermark. Very small watermarks are easy to crop out. Very large ones obscure the content too much.
