How to open a .pub file without Publisher.

First, identify the file

A file ending in .pub is usually a Microsoft Publisher document. It might be a flyer, newsletter, label sheet, invitation or template. Make a copy before trying an unfamiliar program, particularly if the file is the only surviving version. Check its size and name, and keep it in its original folder so you can still find related images or later revisions.

If your computer offers to open it in another app, that does not mean the app can read Publisher's layout correctly. A result that opens is only the first step. You still need to inspect every important page.

Could someone still export it for you?

If a trusted colleague or family member has a working copy of Publisher, ask them to open the file and export a PDF. For a few files, this is often the clearest way to get a readable copy. Ask for the original .pub back as well as the PDF, and compare the page count. If you will need edits, discuss which parts must remain editable before choosing a new format.

Publisher is removed from Microsoft 365 on 1 October 2026. One-off versions can continue to run after support ends on 13 October, without further updates. The guide to Publisher's retirement explains those dates and the export options.

Try an office or drawing program

Some free office suites import .pub files. This may be enough for a simple one-page notice. Open a copy, then check that the page dimensions, text and images match what you expect. If you have an old printed copy or a Publisher PDF, place them beside the new output for comparison.

The main risks are shifted text, missing fonts, repeated paragraphs from linked text boxes, and old images that draw incorrectly. These problems can be subtle in a thumbnail. Zoom in on small text and inspect the page edges before exporting a new PDF.

Understand online converters

A website may offer to open or convert a .pub file after you upload it. Before you do, consider what is inside. Old parish directories, school newsletters and client materials can contain personal details. Read the service's retention terms, file limits and deletion policy. If the file is sensitive, an upload may be unsuitable.

Even for a non-sensitive file, test the result. A converter may produce a PDF you can read but cannot edit, or may lose layout details. Avoid sending a whole archive to a service until you have checked representative files and know where the data goes.

Use a local reader and converter when available

PUB Rescue is being finished as a Windows app that reads .pub files without Publisher. It converts on your own computer to PDF and PowerPoint with editable text, and produces a report describing what did not come across exactly. You can point it at one file or a whole folder, and your original files remain unchanged.

It is currently on a waitlist, so do not expect a download or purchase link yet. The planned free trial will let you check your own PDF output with a watermark. If you need to edit text, the licensed editions include the PowerPoint output.

Verify the document you recovered

Start with the number and size of pages. Read the first and last paragraphs and a section where text flows between boxes. Inspect tables, logos and small print. A missing font can change line breaks enough to hide a sentence at the bottom of a box. If a tool supplies a report, read it and check the specific pages it names.

Keep the original .pub even after you have a PDF. A later converter might read a difficult page better, and the original is your record of what was created. The PDF guide explains archiving.

The PowerPoint guide covers files you still need to edit.

For many files, use the folder guide to organize the work.
