Watermark PDF Online: Protect Your Intellectual Property

In the digital age, sharing documents is easier than ever, but so is unauthorized copying and distribution. Whether you are a photographer sharing a portfolio, a business sending a draft contract, or a student submitting a thesis, you need a way to claim ownership. Our Watermark PDF Tool allows you to stamp your documents with a custom text or logo overlay, ensuring everyone knows the source and status of the file.

This tool is entirely browser-based, meaning you can add "CONFIDENTIAL", "DRAFT", "COPY", or your own company logo to every page of your PDF in seconds without installing expensive software.

Why Add a Watermark to PDF?

Watermarking serves multiple critical functions in document management:

• Copyright Protection: Prevent others from claiming your work as their own. A visible watermark makes it clear who the original author is.
• Status Indication: Clearly mark documents as "DRAFT," "SAMPLE," or "APPROVED" to avoid confusion during the review process.
• Brand Enforcement: Adding your company logo to every page of a report or ebook reinforces your brand identity and makes your document look more professional.
• Security Deterrent: While not a hard lock like encryption, a watermark acts as a visual deterrent against unauthorized printing or sharing of sensitive materials.

How to Watermark a PDF Online

We designed this tool to be visual and interactive ("What You See Is What You Get"):

1. Upload Your Document

Drag your PDF file into the blue upload box. The first page will load in the preview area.

2. Customize Your Stamp

Choose between Text or Image mode:

• Text: Type your message (e.g., "Do Not Copy"). Adjust the font size, color, and rotation angle.
• Image: Upload your logo or a custom stamp image. PNG files with transparent backgrounds work best.

3. Position and Apply

Drag the watermark to exactly where you want it on the page. Use the opacity slider to make it semi-transparent so it doesn't block the text underneath. Click "Apply to All Pages" to stamp the entire document and download.

Key Features of Our Tool

• Batch Application: You only need to place the watermark once on the preview. Our tool automatically replicates it on every single page of the PDF.
• Transparency Control: Adjust the opacity/transparency level to ensure the watermark is visible but doesn't make the document unreadable.
• Smart Positioning: Drag and drop functionality gives you total freedom over placement—center, corner, or diagonal.
• Privacy First: Your files are processed securely via SSL and are deleted from our servers immediately after the download link is generated.
• Cross-Platform: Watermark PDFs from your iPhone, iPad, Android phone, Mac, or Windows PC. No installation required.

Frequently Asked Questions (FAQ)

Can I watermark only specific pages?

Currently, our tool applies the watermark to all pages for consistency. This is the most common requirement for document protection.

Does this work on Mac and Mobile?

Yes! Since it runs in the browser, you can watermark PDFs from your iPhone, iPad, Mac, or Android device effortlessly.

Will the watermark be removable?

We "bake" the watermark into the PDF layers. While advanced editing software might be able to remove it, it is permanent enough for standard sharing and printing purposes.
