Publisher is included in higher-end editions ofMicrosoft Office, reflecting Microsoft's emphasis on the application as an easy-to-use and less expensive alternative to the "heavyweights" with a focus on the small-business market, where firms do not have dedicated design professionals available to make marketing materials and other documents.[5][6] However, it has a relatively small share of the desktop publishing market, which is dominated byAdobe InDesign and formerly byQuarkXPress.[5]
On February 15, 2024, Microsoft announced that Publisher will be discontinued on October 13, 2026.[8][9] On the specified date, Publisher will no longer be included inMicrosoft 365 plans, and existing on-premises installations will no longer be supported. This date will mark the end of Publisher as a standalone Microsoft program since its initial release in 1991.
Several applications can import Publisher'sproprietary file format (.pub) for editing with some success, includingCollabora Online,[10]LibreOffice,[11] andScribus.[12] Another option is to save the document as a separate EPS file for each individual page in the publication, and to then open the EPS files in the aforementioned applications or other applications.[13]
Publisher supports some other file formats, including Microsoft'sEnhanced Metafile (EMF) format, which is supported on Windows platforms. The Microsoft Publishertrial version can be used to view .pub files beyond the trial period.[14][15]
Aldus (later Adobe) PageMaker also saved files with a .pub extension, but the two file formats were unrelated and incompatible.
