Rich text refers to a format that allows for enhanced text presentation beyond plain text. It includes features like different fonts, colors, sizes, and styles such as bold or italic. This formatting makes it easier to emphasize important information and improve the overall visual appeal of the text. Rich text is commonly used in applications like word processors and email clients, enabling users to create more engaging documents. It often supports additional elements like images, hyperlinks, and lists, making it versatile for various types of content. Examples of rich text formats include RTF and HTML.
