📄 Publisher file won't open on iPad
iPadOS has no native support for Microsoft Publisher (.pub) files, and Microsoft never released a Publisher app for iPad. To view or share a Publisher file on iPad, you need to convert it to PDF first — which is exactly what OpenAny does, free, no account required.

About .pub to PDF conversion
Why can't I open a .pub file on my iPad at all?
Microsoft Publisher is a Windows-only desktop application and Apple's iPadOS has no built-in ability to read the .pub format. Unlike Word or Excel, Microsoft never brought Publisher to iPad or released any iOS app for it. There is no workaround that lets you open the raw .pub file on iPad — you need to convert it to a format like PDF first.
How do I convert a Publisher file to PDF so I can open it on my iPad?
Upload your .pub file to OpenAny.io, select PDF as the output format, and download the result. The converted PDF will open in any iPad PDF viewer, including the built-in Files app, Safari, or apps like Adobe Acrobat. Your file is deleted from our servers within 60 seconds of conversion.
Will the converted PDF look exactly like the original Publisher file?
For most files it will be close, but Publisher uses proprietary layout features — custom fonts, certain text wrapping styles, and embedded objects — that may not survive the conversion perfectly. Check headings, columns, and any image-heavy sections after converting. If the layout is critical, converting from the original Windows machine using Publisher's own 'Export to PDF' feature will give the most faithful result.
