RTF (Rich Text Format)
RTF (Rich Text Format) is a document format developed by Microsoft that stores simple formatting like bold, italics and fonts alongside plain text. It was the default format of WordPad and early versions of Microsoft Word. Because RTF files can be read as text, they open in almost any word processor.
Use RTF when you need basic formatting in a document that must open in older or minimal word processors. It is a good bridge when the exact software on the receiving end is unknown.
