What is a PUB (Microsoft Publisher Document) file?

Microsoft Publisher Document (PUB) is the native format of Microsoft Publisher, a desktop-publishing application aimed at newsletters, brochures, flyers, greeting cards, and other page-layout work. Unlike Word, Publisher treats a page as a canvas of independently positioned text boxes and graphics, giving precise control over layout. A PUB file stores that arrangement along with the text, images, and print settings. Microsoft has announced that Publisher will be retired in October 2026.

How to open a PUB file?

Microsoft Publisher, included with some Microsoft 365 plans on Windows, is the only application that renders PUB files exactly as designed.

No other application reproduces Publisher’s full feature set — LibreOffice Draw imports many PUB files, though complex layouts often shift. The most dependable approach is to ask the sender to export the document as a PDF from Publisher, which preserves the layout perfectly and opens anywhere. Our PUB to PDF tool can also do the conversion.

What is a PDF (Portable Document Format) file?

The Portable Document Format (PDF) is a universal file format that comprises characteristics of both text documents and graphic images which makes it one of the most commonly used file types today. The reason PDF is so widely popular is that it can preserve original document formatting. PDF files always look identical on any device or operating system.

How to open a PDF file?

Most people head right to Adobe Acrobat Reader when they need to open a PDF. Adobe created the PDF standard and its program is certainly the most popular free PDF reader out there. It's completely fine to use, but I find it to be a somewhat bloated program with lots of features that you may never need or want to use.

Most web browsers, like both Chrome and Firefox, can open PDFs themselves. You may or may not need an add-on or extension to do it, but it's pretty handy to have one open automatically when you click a PDF link online. I highly recommend SumatraPDF or MuPDF if you're after something a bit more. Both are free.
