How to Open a Pub File on iPhone: Step-by-Step Guide

Opening a PUB file on an iPhone may seem like a daunting task, but it’s actually quite simple with the right tools. All you need is a compatible app that can open and read PUB files. Once you have that, you can easily access and view the content of your PUB file right on your iPhone.

After you successfully open a PUB file on your iPhone, you’ll be able to view the document just as you would on a computer. This means you can see all the text, images, and layout that the file contains, making it easier to work with the document on-the-go.


Have you ever been in a situation where someone sends you a PUB file and you can’t open it because you’re not at your computer? Or perhaps you’re trying to show off your latest project on your iPhone, but the file just won’t cooperate. Fret not, because opening a PUB file on an iPhone is not as complicated as it sounds.

PUB files, short for Publisher files, are commonly used for documents that require a layout, such as newsletters, brochures, and posters. They are created by Microsoft Publisher, a desktop publishing application. However, the iPhone does not natively support PUB files, which can be a bit of a pickle for iPhone users.

Why is it important to know how to open a PUB file on an iPhone? Well, we live in an age where everything is mobile, and being able to access documents on-the-go is crucial. Whether you’re a student, a business professional, or just someone who needs to view a PUB file without access to a computer, knowing how to open it on your iPhone can save the day. It’s relevant to anyone who uses an iPhone and may need to view or edit documents in a PUB format.

Step by Step Tutorial: How to Open a PUB File on iPhone

Before we dive into the steps, it’s important to note that opening a PUB file on your iPhone will allow you to view and, in some cases, edit the document directly from your mobile device. This means you no longer have to be tethered to your computer to work on a Publisher document.

Step 1: Download a Compatible App

First and foremost, find and download an app that can open PUB files.

There are several apps available on the App Store that can open PUB files, such as Microsoft Word or a third-party app like File Converter. Make sure to download an app that not only opens the file but also retains the formatting.

Step 2: Locate the PUB File

Locate the PUB file you need to open on your iPhone.

The file could be in your email, cloud storage, or sent via a messaging app. If it’s an email attachment, download it to your phone.

Step 3: Open the PUB File with the App

Open the PUB file using the app you downloaded.

Once you’ve located the file, tap on it and select ‘Open in…’ and choose the app you installed. The document should then open within the app.

Additional Information

When it comes to opening PUB files on an iPhone, there are a few additional things to keep in mind. First, not all apps are created equal. Some may be better at retaining the original formatting of your document, while others may change the layout or font. It’s important to read reviews and possibly test a few different apps to find the one that works best for you.

Another tip is to keep your PUB files in a cloud storage service like iCloud, Dropbox, or Google Drive. This way, you can easily access them from any device, including your iPhone, without having to transfer the files each time you need them.

Finally, remember that while opening a PUB file on your iPhone is convenient, it may not always be the best way to work on a document. If you need to make extensive edits or work on a complex layout, you’ll probably be better off using a computer with Microsoft Publisher.
