Introduced Unicode RTF, which supports 16-bit Unicode character encoding scheme defined inclusion of PNG, JPEG and EMF picture types in hexadecimal (the default) or binary format in a RTF file. It also supported inclusion of the Windows Metafile, PICT, Windows device-dependent bitmap, Windows device-independent bitmap and OS/2 Metafile image types in RTF.Īllowed for font embedding, which lets font data to be located inside the file.ġ/94 GC0165 for device-independence and interoperability, encouraged embedding bitmaps within Windows Metafiles, instead of using Windows device-independent bitmaps or Windows device-dependent bitmaps.

The 1992 revision defined support for Microsoft Object Linking and Embedding (OLE) objects and Macintosh Edition Manager subscriber objects. RTF specifications for Microsoft Word RTF version RTF files were used to produce Windows Help files, though these have since been superseded by Microsoft Compiled HTML Help files. Microsoft anticipates no further updates to RTF, but has stated willingness to consider editorial and other non-substantive modifications of the RTF Specification during an associated ISO/IEC 29500 balloting period. Microsoft has discontinued enhancements to the RTF specification, so features new to Word 2010 or a later version will not save properly to RTF. The final version was 1.9.1 in 2008, which implemented features of Office 2007. All subsequent releases of Microsoft Word for Macintosh, as well as all Windows versions, can read and write in RTF format. The first RTF reader and writer shipped in 1987 as part of Microsoft Word 3.0 for Macintosh, which implemented the RTF version 1.0 specification. Richard Brodie, Charles Simonyi, and David Luebbert, members of the Microsoft Word development team, developed the original RTF in the middle to late 1980s. RTF should not be confused with enriched text or its predecessor Rich Text, nor with IBM's RFT-DCA (Revisable Format Text-Document Content Architecture), as these are different specifications. There are several different revisions of RTF specification portability of files will depend on what version of RTF is being used.

Most word processors are able to read and write some versions of RTF. Prior to 2008, Microsoft published updated specifications for RTF with major revisions of Microsoft Word and Office versions. The Rich Text Format (often abbreviated RTF) is a proprietary document file format with published specification developed by Microsoft Corporation from 1987 until 2008 for cross-platform document interchange with Microsoft products.
