How to open PUB files without Publisher
If you have .pub files but no longer have Publisher, the safest approach is to create modern copies before you need them urgently.
Your practical options
You can look for an older computer with Publisher installed, ask the original creator to export the file, or use a conversion service that can create PDF and editable PowerPoint copies.
For a large folder of files, a rescue workflow is usually faster than manual one-by-one exports.
Why PDF and PowerPoint help
PDF keeps a reliable viewable copy. PowerPoint gives many teams an editable format they already know how to use.
