A desktop publishing application from Microsoft that focuses on page layout and graphic design.
Microsoft has announced that Publisher will reach end of life in October 2026. After October 1, 2026, it will no longer be included in Microsoft 365, and Microsoft 365 subscribers will no longer be able to open or edit Publisher files in the Publisher app. Until then, Publisher continues to work with its current functionality.
The available guidance is:
- Continue using Publisher as-is until October 1, 2026.
- Convert important
.pubfiles before that date:- To preserve viewing, open the file in Publisher, then go to File > Save as > choose PDF.
- To continue editing, open the PDF in Word using File > Open, then confirm the conversion. Microsoft notes that the converted Word file is optimized for text editing, so the layout can differ from the original, especially for graphics-heavy documents.
- For large numbers of files, bulk conversion to PDF can be automated with a PowerShell script.
- For common Publisher scenarios, Microsoft recommends other Microsoft 365 apps. For example, newsletters, envelopes, labels, and programs map mainly to Word, while banners, signs, and posters map mainly to PowerPoint.
If the goal is to continue using Publisher beyond Microsoft 365 availability, the context states that a perpetual version can still be installed and used beyond October 2026, although support will end.
