How it works

  1. Choose a PDF, select text or a PNG/JPG image, and configure ranges, position, size, opacity, and rotation.
  2. Export a new PDF with the mark drawn onto selected pages; the source is not changed.

How it helps

Use watermark pdf to complete a focused document task without changing the original file.

Input and output

Supported input. One readable PDF and, for image watermarks, a PNG or JPG. PDF limits are 5 MB/100 pages on Free, 20 MB/500 pages on Pro, or 50 MB/2,000 pages on Business.

Output. A PDF containing the selected visible watermark as page content.

What it cannot do yet

  • A watermark is not a security feature or guaranteed anti-copy mechanism.
  • SVG, WEBP, animated images, and unsupported transparency behavior are not guaranteed.
  • The tool does not detect existing marks or avoid page content automatically.

Privacy and processing

The PDF and supported image are combined locally in the browser. This workflow does not upload documents or require an account.

Frequently asked questions

Why is the watermark hard to see?

Increase opacity or size, choose a clearer position, and check the preview against the page background.

Why was my image rejected?

Use a non-animated PNG or JPG that your browser can read.
