With just a few clicks, you can add text to a PDF, insert an image watermark, and customize it to suit your needs—completely free, no sign up needed, no installation needed.

Why Use a Watermark in a PDF?

A watermark PDF document contains a semi-transparent text or image overlay that serves various purposes:

• Copyright Protection – Prevents unauthorized use or sharing.
• Branding – Adds company logos or signatures for professional documents.
• Confidentiality – Marks files as “Confidential” or “Draft” to avoid leaks.
• Discourages Unauthorized Editing – Watermarks make it harder for users to modify documents.

An online free watermark PDF tool allows you to apply these marks instantly without downloading any software.
