How to Add a Watermark to a PDF

Adding a watermark to a PDF is one of the most effective ways to protect and brand your documents. Whether distributing contracts, sharing drafts, or protecting intellectual property, a watermark signals ownership and deters misuse.

Our tool lets you upload your PDF, configure a text or image watermark, and download the result in seconds — no software to install and no account to create.

Text Watermark vs. Image Watermark

A text watermark is the most versatile option. Type any word or phrase — “CONFIDENTIAL”, “DRAFT”, your company name, or a copyright notice. Control font size, colour, bold/italic formatting, and rotation angle.

An image watermark lets you stamp a PNG or JPG logo directly onto every page. Scale the logo by percentage of page width, set the opacity so it does not obscure content, and choose its position precisely.

Why Watermark Your PDF?

Watermarks establish authorship on shared documents, mark files as “DRAFT” or “CONFIDENTIAL” to control distribution, discourage screenshot theft, and add a professional layer of trust to contracts and proposals.
