Your .pub files, on a Mac.

Open Microsoft Publisher documents without Publisher. Save them as PDF, or as files you can keep editing in Affinity or InDesign. Your originals are never changed.

Not out yet. What to do with your files meanwhile, or get one email when it is approved.

Publisher leaves Microsoft 365 on 1 October 2026.

Microsoft's own advice is to convert your files before then. If you have a folder of .pub files, a Mac, and no Publisher, this is the app for that.

The dates and what they mean

Built for the part everything else gets wrong.

Stories stay in order across pages

Newsletters use linked text boxes: one story runs from page 1 into page 3. The open-source parser inside LibreOffice and PubHarbor has never implemented that link, so it pastes the whole story on every page and leaves the last one blank; that bug has been open since 2013, and PUB Reader's reviews describe the same symptom. PubFile follows the links, so page 2 starts where page 1 ended.

Files you can keep editing

PubFile writes IDML, the exchange format that Affinity (free), Affinity Publisher 2 and Adobe InDesign open. Text stays text, boxes stay boxes, pictures come along in a folder.

Nothing leaves your Mac

No upload, no account, works offline. Parish directories and class lists stay where they are. Originals are read, never rewritten.

A report that tells you what to check

For every file: which fonts were substituted, how much of each story was placed on each page and what did not fit, and which objects could not be converted. It says what broke instead of reporting zero warnings on a blank page.
