Add Watermark to PDF Free

- Someone with PDF editing tools may be able to alter or remove visible marks.
- Use password protection or access controls when the file itself needs stronger protection.
How it works

- Add the PDF that needs a visible mark.
- Choose text or image watermark mode and adjust opacity, size, rotation, and placement.
- Download the watermarked PDF copy and keep the original unchanged.

Common questions
Can I add a logo watermark?
Yes. Use image watermark mode for logos, seals, or brand marks where supported.
Is a watermark the same as redaction?
No. A watermark is visible text or image content. It does not permanently remove hidden information underneath.
Can I apply a watermark to every page?
The watermark workflow is designed for selected pages and repeated page marking where supported by the tool controls.
