Follow these steps to stamp your logo on a document online
Workers frequently share PDF files containing sensitive information internally with colleagues as well as outside of their organization. One way to deter unauthorized people from reading or reusing your content is by adding a watermark to the document.
This post will show you how to add a watermark to a PDF file online for FREE using the iLovePDF Watermark tool. Scroll down for step-by-step instructions.
What is a watermark?
A watermark is an image, logo, or text which appears in front or behind the content in a document. Traditionally, watermarks have been used on printed documents such as stamps or documents of governmental organizations. Now they are also used on digital assets to protect the content.
Why do we use watermarks on documents?
Watermarks have several different uses. They could be used to identify the person who created the document content, add a stamp of approval, or remind people that the content is confidential and shouldn’t be shared.
You may already be familiar with photographers adding a watermark to images online to take ownership of their photography. People also use watermarks to make content more secure in PDF files.
If you work in a company that handles sensitive business documents, it’s recommended that you watermark PDF files before sending them by email.

What is the difference between a watermark, stamp, and logo?
You might hear these terms used interchangeably. Generally speaking, a watermark refers to an image or pattern that is placed on a document or photo to identify its maker. In most cases, watermarks are placed behind the content so that you can still read it.
A watermark is sometimes referred to as a stamp when it is - as the name suggests - visibly stamped on top of the document content, sometimes hiding the content. Online PDF Editors such as iLovePDF offer the ability to adjust the opacity of the watermark or stamp.
A logo is a graphic design, text, or symbol that identifies a company or its brand or products. Many companies and organizations use their logo as a watermark for copyright purposes.
