Understanding .pub
Best .pub File Viewer for Windows, Mac and Linux
Quick answer
Looking for a .pub file viewer? Compare Microsoft Publisher, Korva, LibreOffice Draw and online viewers for opening Publisher files on Windows, Mac and Linux.
A good .pub file viewer should open Microsoft Publisher documents, show the text and images clearly, export a PDF, and avoid uploading private files. Microsoft Publisher itself is the official viewer while you still have it, but after Publisher's October 1, 2026 retirement, the practical choices are Korva, LibreOffice Draw, or an online converter for low-risk files.
There is no built-in .pub previewer in Windows, macOS, Linux, Chrome, Safari or Edge. A .pub is not an image and not a PDF. It is a Publisher document, stored in a proprietary binary format. That is why double-clicking one usually fails unless Publisher or another compatible tool is installed.
Option 1: Microsoft Publisher
Publisher is the gold standard for viewing .pub files because it made the format. If you still have Publisher, use it to open important files and export PDFs before the end-of-life date.
The weakness is availability. Publisher was Windows-only, it is leaving Microsoft 365, and unsupported old installs are not a durable archive plan. It is a good bridge while it lasts, not the viewer you should rely on forever.
Option 2: Korva Reader and Converter
Korva’s free Reader and Converter tier is a local desktop .pub viewer for Windows, macOS and Linux. It opens Publisher files, shows the recovered page, and exports PDF without requiring an account or upload.
This is the right fit when:
- you do not have Publisher installed
- you are on Mac or Linux
- the file is private
- you need a PDF copy
- you may later want to edit the layout
Korva’s importer recovers text and embedded images and lays them onto a clean editable page. It is not promising a perfect clone of Publisher’s undocumented geometry. It is built to recover the useful contents and let you save or export them.
Option 3: LibreOffice Draw
LibreOffice Draw can open some .pub files using the libmspub import filter. It is free, open source and local, so it deserves a place on the shortlist.
The limitation is consistency. Some files import well. Others arrive with shifted objects, missing images or odd text flow. For simple public files, try it. For an important archive, compare the result carefully before assuming it is good enough.
Option 4: Online viewers and converters
Online .pub viewers usually work by uploading the file, converting it server-side, then showing a PDF or image preview. That can be convenient, but it is not neutral. You are sending the file to someone else.
Use online viewers only for non-sensitive documents. Avoid them for member lists, school documents, client drafts, internal notices, donor material or anything confidential.

Do you need a viewer or an editor?
If the goal is only to see what is inside, view the file and export a PDF. A PDF is the durable copy you can email, print and archive.
If you need to change names, dates, images or layout, a viewer is not enough. Korva’s free desktop app recovers the .pub content onto an editable page and exports PDF. Korva Pro adds editable .kva saves, master pages and mail merge.
.pub viewer, try LibreOffice Draw for a free second opinion, and keep online viewers away from private files.For more background on the format itself, read what a .pub file is. For a practical conversion walkthrough, use how to open a .pub file without Publisher or convert .pub to PDF.
Frequently asked questions
Is there an official free Microsoft Publisher viewer?
No. Microsoft does not ship a separate free Publisher Viewer like it once did for some Office formats. Publisher itself is the official app, and it retires on October 1, 2026.
What is the best .pub file viewer if I do not have Publisher?
For private files, use a local viewer such as Korva or LibreOffice Draw. Korva is purpose-built for .pub recovery and has a free Reader and Converter tier. LibreOffice Draw is free but import fidelity varies.
Can I view .pub files on a Mac?
Yes, with a third-party app. Microsoft Publisher never ran natively on Mac, but Korva has a macOS build that opens .pub files and exports PDFs locally.
Can a browser view .pub files?
Not by default. A browser can view the PDF after conversion, but it cannot open a raw Publisher .pub file unless a web service uploads and converts it first.
Do I need editing, or just viewing?
If you only need to read or print the file, export it to PDF. Korva's free desktop tier also lets you change dates, names, images or layout before export. Korva Pro is only needed to save the editable project or use repeat-work tools.
