Whether you're marking a document as a draft, protecting your photography, or branding files with your logo, adding a watermark is one of the simplest ways to label and protect your content. Here's how to do it for free — on PDFs and images alike.

Why Add a Watermark?

Watermarking serves several practical purposes:

  • Draft labeling — Mark documents as "DRAFT" or "SAMPLE" before finalizing
  • Confidentiality — Stamp sensitive documents with "CONFIDENTIAL"
  • Branding — Add your company logo to shared documents
  • Copyright protection — Discourage unauthorized use of photos or designs

Tips for Best Results

💡 Pro Tip

Keep opacity between 20-40% so the watermark is visible but doesn't obscure the content underneath.

Single Stamp vs Tiled Watermark

Choose the approach based on your goal:

  • Single stamp — A clean, subtle watermark in one corner or the center
  • Tiled / Repeat — Copies spread across the whole page, harder to crop out — better for protecting content from misuse

Text vs Logo Watermarks

Text watermarks work well for quick labels like "DRAFT" or "CONFIDENTIAL." Logo watermarks are better for branding — use a transparent PNG logo for the most natural-looking result.
