Add a Watermark to PDF Documents

Last updated: March 1, 2026

Need to mark a document as DRAFT, CONFIDENTIAL, or SAMPLE before sharing? OneClickPDF's free watermark tool adds text or image watermarks to every page of your PDF — with full control over position, size, rotation, opacity, and color. No Adobe Acrobat needed, no account required.

The Problem

You need to share a document but make it clear that it's a draft, contains confidential information, or is a sample copy. Without a watermark, recipients might treat a draft as final or redistribute a confidential document. Adding watermarks in Word or design tools means converting back to PDF, which can break formatting.

How It Works

1

Open the Watermark tool

Go to OneClickPDF's Watermark PDF page.

2

Upload your PDF

Drop your document onto the upload zone.

3

Configure your watermark

Choose text watermark (type any text like DRAFT, CONFIDENTIAL, DO NOT COPY) or upload an image (company logo, stamp). Adjust position, size, rotation, opacity, and color to match your needs.

4

Preview and download

Preview the watermarked pages, then download. The watermark is embedded on every page of your PDF.

Frequently Asked Questions

Can I use my company logo as a watermark?
Yes. Upload any PNG or JPG image as a watermark. Adjust its size, position, opacity, and rotation for professional results.
Can I make the watermark semi-transparent?
Yes. The opacity slider lets you make the watermark as subtle or prominent as you want — from barely visible to fully opaque.
Is the watermark on every page?
Yes. The watermark is applied consistently across all pages of the document.
Can the watermark be removed by recipients?
The watermark is embedded in the PDF content. While it's not encrypted protection, it clearly marks the document's status. For stronger protection, combine with password protection using our Protect PDF tool.

Protect your documents with professional watermarks in seconds. Whether it's a draft disclaimer, a confidentiality stamp, or your company logo, OneClickPDF applies it consistently across every page — free and private in your browser.
