Add a watermark to your PDF

Our tool lets you watermark PDF documents. You can protect your files, mark copyright details, or add confidentiality stamps to your pages in seconds without installing extra software.

How to add a watermark to a PDF

Use our editor to put a watermark on PDF files:

Step 1. Upload your document

Drag and drop your file into our workspace or upload area. You can also select the document directly from your computer or phone.

Step 2. Enter your text

Create a custom message for your pages and enter it in the designated text box. You can use status labels like "Confidential," "Draft," or "For Internal Use Only." You can also enter your company name or brand details.

Step 3. Customize the appearance

Adjust the visual settings. Choose the font style, text size, and color that you want. Make the text semi-transparent with opacity controls. That way, your main content stays readable.

Step 4. Apply and download

Check the preview to see how the text looks on your pages. Add the watermark to your document. After that, you can download the final version of the PDF to your computer or phone.

Draft & confidential watermarks

Our editor displays "Hello World" as the default text. You can replace this phrase with any custom label.

Adding a draft watermark or the word "Confidential" helps manage document status in standard business workflows. For example, you may share early document versions with the "Draft" watermark. This one word helps prevent team members from using unfinished content. The "Confidential" watermark flags sensitive information.

You can also type custom notices, author names, or even dates.

Customize font size, opacity, and text color

Our platform allows you to edit watermark in PDF files, so the text fits your layout. Here are several visual settings that you can modify directly inside our editor:

• Opacity and transparency: Lower the opacity level to make your text semi-transparent. This keeps your background text and original graphic images clear and understandable.

• Font size and scaling: Increase or decrease text size to fit small document pages or large technical drawings.

• Text color: Choose any color you like. It is better to use dark shades on light pages and a lighter tone for dark backgrounds to keep your label prominent.

Why add a watermark to a PDF

A watermark on a document gives more context before you share files with your clients and other teams. Here are the main reasons to use them:

1. Protect intellectual property and branding

Adding a logo, company name, or copyright text helps protect your work from copying. It shows ownership across reports, presentations, and guides. Readers can instantly identify your content when they see those documents.

2. Indicate document status

Labels like "Draft," "Pending Approval," or "Sample" clarify the stage of your project. This helps your team members avoid accidentally sending early versions to clients. It also prevents your team from mixing up temporary notes with final files. Everyone can quickly tell if a document is ready for use by looking at the watermarks.

3. Mark sensitive material before distribution

Stamps like "Confidential" or "Internal Use Only" warn readers about sensitive data. Adding these markers before emailing contracts or financial sheets helps protect private information.

4. Prevent content misuse and unauthorized sharing

Adding recipient names, project dates, or specific identifiers helps manage file distribution. Clear visual overlays discourage readers from copying, printing, or sharing your files without permission.

Watermark a PDF on any device

You can add watermark in PDF files online from any standard web browser, so you do not need to install software, apps, or extensions.

Our watermark maker works across all major operating systems and browsers:

Your files stay private

We prioritize your privacy whenever you create or add a PDF watermark in our workspace. Every file is processed through secure, encrypted connections to protect your data.

Your documents remain strictly private and accessible only to you inside your session. These privacy protections apply to all your content, including corporate reports, legal agreements, and personal records.

More PDF tools

Adding text watermarks is just one way to update your files. If you want to add logo to PDF pages instead of plain text, use our Add Image to PDF tool. This feature lets you place logos, visual stamps, or digital signatures onto any page.

Watermarks show document ownership and status, but they do not cover up the text underneath. When you work with sensitive data, a text overlay might not be enough. People often ask how to protect the watermark in PDF files, so readers cannot see private details behind the stamp. If you need to hide account numbers or personal records, use our PDF Redactor. It permanently removes confidential text and images from your pages so no one can access them.
