How to open a .pub file without Microsoft Publisher
The .pub format really only opens with Microsoft Publisher, and Publisher was retired on October 13, 2026. Here are every real path, free and paid, with their limits stated honestly.
The short answer
- A few files, simple layout: try LibreOffice Draw (free, limited fidelity).
- A whole archive, layout matters: PublisherRescue converts them all to faithful PDFs, with free previews.
- You know someone with Office 2021: their Publisher still works and can export to PDF.
Why the .pub file won't open
.pub is the proprietary format of Microsoft Publisher, the page-layout app bundled with Office for years. Unlike Word or Excel, no other program reads it reliably: not Google Docs, not Pages, not Canva. Anyone who receives a .pub without Publisher, simply can't open it.
Since October 13, 2026 the problem hits Publisher users too: Microsoft removed the app from Microsoft 365, and subscribers can no longer open or edit their files with it. Only perpetual licenses (Office 2021 and earlier) still work, without updates. The files themselves are intact: what is missing is a program that reads them.
Option 1: LibreOffice Draw (free)
LibreOffice is a free, open-source suite whose Draw module can import many .pub files. How to try: install LibreOffice, open Draw, drag the .pub into the window. On simple documents (text, a few images) the result may be enough.
The honest limits: the importer does not use Publisher's engine, so WordArt, tables, decorative borders, exotic fonts and grouped objects often shift or change look. On elaborate newsletters and flyers, the result rarely stands without touch-ups. And for hundreds of files, it remains manual work, one at a time.
Option 2: generic online converters
Free websites can turn .pub into PDF. For one or two files, with patience, they may do: almost all work one file at a time, with waiting queues and daily limits, and use non-native conversion methods, same fidelity issues as LibreOffice. Watch where your files end up too: not all clearly state where they process them and when they delete them.
Option 3: convert the whole archive to faithful PDFs
If files are many, or the layout must remain exact (the association newsletter, the menus, the small-business flyers), the right route is to convert the entire archive to PDF once: PDF opens everywhere, forever, and prints identically.
That is exactly what PublisherRescue does: you upload your files (whole folders or ZIPs too), the service runs a high-fidelity conversion pipeline, i.e. with the original print-quality output, and gives you back an ordered archive with a faithful PDF for each document and an editable PowerPoint, on every plan. Previewing every file is free: you see the result before you pay. Files are processed in Europe and deleted after 7 days.
Open .pub files on Mac
Publisher was never released on Mac. If you are on Mac only, three ways: LibreOffice Draw (free, opens many .pub files directly), an online converter for one or two files, or PublisherRescue if you have a whole archive and want faithful PDFs without installing anything.
Open .pub files on iPhone and iPad
No iOS app opens .pub natively. The practical fix: convert the file to PDF (on your computer or via PublisherRescue), then the PDF opens in Preview, Files, or any PDF reader. Don't waste time looking for dedicated apps: the format is too niche.
Open .pub files on Android
Same as iOS: no Android app opens .pub well. PDF is the way. If you have many files from a former school or association archive, bulk conversion is the only realistic option.
What if I need to edit the documents?
PDF preserves, but does not edit easily. If some documents still need to be "live" (next month's newsletter), two routes: content recovery (text and images extracted, to rebuild in Word or Canva) or layout rebuild in PowerPoint, which like Publisher works with free objects on the page. Both are PublisherRescue add-ons on top of the PDF.
Have a folder full of .pub files?
Upload them and preview every file for free. You pay only if you download the archive.

Frequently asked questions
Publisher no longer opens. Are my .pub files lost?
No. The files are unchanged on your disk. What is gone is the app that read them. They can still be opened with LibreOffice Draw or converted to PDF and PowerPoint.
Can I still open .pub files after October 2026?
Depends on your version. With Microsoft 365, no: since October 13, 2026 Publisher is disabled. With a perpetual license (Office 2021 or earlier) it still works, without updates. If you have neither, you need a conversion.
Can I convert a .pub file to Word?
Yes, but Word thinks in text flow while Publisher places objects freely: you recover text and images, not the layout. For a faithful result, PDF is the right format.
Does LibreOffice open .pub files?
Many yes, free of charge, with the fidelity limits above. Worth trying for a few simple files.
I have hundreds of files: how do I convert them all?
With free tools, one at a time: days of work. PublisherRescue converts the whole archive in one go and returns everything ordered.
Are my files safe if I upload them?
On PublisherRescue files are automatically deleted after 7 days, with email confirmation. Every preview is free, so you can check the result before you pay.
