Add Watermark to PDF

Whether you're sharing sensitive business documents, sending draft proposals, or distributing creative work, adding a watermark provides an extra layer of protection and professionalism. PDF watermarking lets you overlay text, logos, or custom graphics onto your document pages, making it clear who owns the content or what stage the document is in.

Best practices for watermarking PDFs

1. Choose the right opacity: Set transparency between 20-40% for subtle protection, or higher for prominent marking.
2. Consider watermark placement: Center or diagonal placement works best for protection, corners for subtle branding.
3. Use vector graphics: For image watermarks, use PNG with transparency for best results.
4. Preview before applying: Check how your watermark looks on sample pages before finalizing.
5. Keep text readable: Ensure watermark text is clear but doesn't obscure document content.
