📄 convert Publisher to PDF on iPhone
iPhones have no native support for Microsoft Publisher (.pub) files — iOS won't open them, and there's no Publisher app for iPhone. The practical solution is to convert the .pub file to PDF first, which you can do on any device with a browser.

About .pub to PDF conversion
Can I convert a Publisher file to PDF directly on my iPhone?
Not with any app installed on the phone itself, since Microsoft Publisher only runs on Windows. However, you can do it through a browser: go to OpenAny.io on your iPhone's Safari or Chrome, upload the .pub file, and download the resulting PDF. No app install or account needed.
How do I get the .pub file onto OpenAny if it's in my email or Files app?
On OpenAny.io, tap the upload area and iOS will let you choose from Files, iCloud Drive, or your email attachments directly. If the file came as an email attachment, save it to Files first by long-pressing the attachment and tapping 'Save to Files', then select it from there.
Will the converted PDF look exactly like the original Publisher file?
Usually close, but Publisher uses proprietary layout features that don't always translate perfectly — custom fonts and complex text wrapping are the most common issues. If exact fidelity matters, the most reliable route is to have someone open the original .pub in Publisher on Windows and export it to PDF from there, since that uses Microsoft's own engine.
