PDF Watermark Tool

What is a Watermark?

A watermark is text or an image that gets stamped onto your PDF pages. You have probably seen "CONFIDENTIAL", "DRAFT", or a company logo sitting in the background of a document. It is a quick way to mark ownership, show a document's status, or stop people from passing off your work as their own.

When Do People Add Watermarks?

• Draft Documents: Put "DRAFT" on documents you are still working on so nobody treats them as final.
• Confidential Files: Add "CONFIDENTIAL" to reports, proposals, or contracts before sharing them externally.
• Copyright Protection: Stamp your name or business name on documents you are distributing so people know who made them.
• Sample Documents: Add "SAMPLE" to templates or examples so they are not used as real documents.
• Branding: Add your company logo or name to PDFs you send to clients.

How to Add a Watermark

1. Upload your PDF using the "Upload PDF" button — a preview of your pages appears.
2. Type your watermark text in the "Watermark Text" field.
3. Set the transparency (0.1 = very faint, 1.0 = fully solid), font size, and position (x,y coordinates, e.g. 100,150).
4. Click "Add Watermark to All Pages".
5. Click "Download Watermarked PDF" to save the result.

Quick Tips

Q: What format do I use for position?
A: Enter it as two numbers separated by a comma, like 100,150. This places the watermark 100 points from the left and 150 from the top.

Q: Can I control how faint the watermark looks?
A: Yes. Transparency of 0.3 gives a light background mark. Set it to 1.0 for a full-opacity stamp.

Q: Does this work on all PDFs?
A: It works on standard PDFs. Password-protected files cannot be opened without removing the password first.
