# MAUI PDF annotation library

Our MAUI PDF annotation library offers the ability to create, remove, and edit annotations through the user interface (UI). It also offers developers access to web APIs for programmatic annotation management.

## What are annotations?

Content displayed as a PDF page isn’t suitable for easy editing, but the PDF specification defines a comprehensive set of objects that can be added to PDF pages without changing the page content. These objects are called annotations, and their purpose ranges from marking up page content to implementing interactive features such as forms.
