A Rich Text Editor (RTE) is a software tool that allows users to create and format text in a visually appealing way. Unlike plain text editors, RTEs enable users to apply various styles, such as bold, italics, and different font sizes, as well as insert images, links, and lists. This makes it easier to produce documents that are not only informative but also engaging. RTEs are commonly used in applications like word processors, content management systems, and email clients. They often feature a toolbar with icons for formatting options, making it user-friendly for individuals without technical expertise. Popular examples of RTEs include TinyMCE and CKEditor.
