What is a PUB file?
PUB is the proprietary file format used by Microsoft Publisher, a desktop publishing application. It contains text, images, layouts, and design elements for creating brochures, flyers, newsletters, and other marketing materials.
Although popular among small businesses and casual users, PUB files have limited compatibility and are best viewed or edited in Microsoft Publisher. Converting them to PDF ensures broader accessibility.
How to open PUB files
PUB files are best opened with Microsoft Publisher. There are limited third-party tools that support PUB files, and viewing them on non-Windows systems is difficult.
Convert PUB to PDF or JPG using AnyConv to ensure compatibility across platforms and easier printing.
