Why Add a Watermark?

Once a PDF leaves your hands, you lose control over where it ends up. A watermark — like "Confidential," "Draft," or your company name — stamped across the pages is a simple visual reminder of ownership or status, and it discourages unauthorized copying or redistribution.

Common Uses for Watermarks

Step-by-Step: Add a Watermark

  1. Open the Watermark PDF tool.
  2. Upload the PDF file you want to protect.
  3. Type in your watermark text (or choose the settings you want).
  4. Apply the watermark — it will be stamped across every page.
  5. Download your watermarked PDF, ready to share securely.

Tips for an Effective Watermark

Keep the watermark text short and legible, and use a light opacity so it doesn't interfere with reading the document underneath. For sensitive files, place the watermark diagonally across the page — it's harder to crop or remove that way.

Is It Safe?

Yes, watermarking happens locally in your browser. Your original PDF is never uploaded to a server during the process.
