Add Watermark to PDF Online
Protect your copyright and label documents as 'Confidential' or 'Draft' instantly.
Protect Your Intellectual Property
Whether you are sending a portfolio to a client, sharing a sensitive internal memo, or publishing an eBook, you need a way to assert your ownership and define the document's status. The most effective way to do this is to watermark PDF files before distributing them.
Our robust utility allows you to easily add watermark to PDF pages with pinpoint accuracy. You can type in a bold "CONFIDENTIAL" text stamp, or upload your company's transparent PNG logo. You have full control over the opacity, rotation angle, and size, ensuring the watermark protects the content without making it impossible to read.
Stamping documents is highly sensitive work. That's why we've engineered our platform to process everything directly inside your browser. No files are uploaded to our servers. Your original documents and your proprietary company logos remain entirely secure on your local hard drive during the whole process.
How to Apply a Watermark
- Upload File: Drag and drop your unprotected PDF into the tool.
- Design Stamp: Choose between a text watermark or an image. Adjust the opacity, scale, and rotation to your liking.
- Apply: Click the stamp button. Your browser will embed the watermark across all pages.

Frequently Asked Questions
Can someone easily remove the watermark I add?
Our tool flattens the watermark into the document's structure. While determined hackers can sometimes extract text, a well-placed image or text watermark significantly deters casual copying and establishes clear ownership.
Can I use my company logo as a watermark?
Absolutely! You can upload any standard image file (like a transparent PNG of your logo) and place it over the document pages. We highly recommend using a PNG with a transparent background for the best results.
