Opening EPUB files on an iPhone can be confusing if you are unfamiliar with the supported apps and methods. Many developers and readers struggle to find the right way to access EPUB ebooks on iOS devices without losing formatting or functionality.
EPUB files are a popular ebook format, and iPhones support them through several apps such as Apple Books and third-party readers. This guide explains how to open EPUB files on iPhone easily, including installation, file transfer, and troubleshooting common issues.
What is an EPUB file and why use it on iPhone?
An EPUB file is a widely used ebook format that supports reflowable text, images, and interactive elements. It is designed for digital reading and is compatible with many devices and apps. On iPhone, EPUB files allow you to read ebooks with adjustable fonts, bookmarks, and annotations.
Developers and readers prefer EPUB because it maintains formatting across devices and supports features like multimedia and accessibility. Using EPUB on iPhone leverages the device’s portability and reading-friendly screen, making it ideal for consuming ebooks on the go.
EPUB files are not natively opened by the iPhone’s Files app but require a dedicated reader app. Apple Books is the default and most integrated option, but third-party apps offer additional features such as advanced library management or support for DRM-protected files.
How do you open an EPUB file on iPhone using Apple Books?
Apple Books is the built-in app on iPhone designed for reading EPUB and PDF files. It provides a seamless experience with syncing across Apple devices and supports bookmarks, highlights, and notes.
To open an EPUB file in Apple Books, you first need to have the file accessible on your iPhone via Mail, Files, or a cloud service. Then, you can import it into Apple Books for offline reading.
Here is how to open an EPUB file using Apple Books:
- Locate the EPUB file in the Files app, Mail, or Safari download.
- Tap the file to preview it.
- Tap the Share icon (a square with an arrow pointing up).
- Select "Copy to Books" or "Open in Books" from the share sheet.
The EPUB file will then open in Apple Books and be saved to your library for future access. This method ensures the file is stored locally and available offline.
What are alternative apps to open EPUB files on iPhone?
Besides Apple Books, several third-party apps support EPUB files on iPhone. These apps often provide additional features such as customizable reading interfaces, library management, and support for DRM-protected content.
Popular alternative EPUB readers include:
| App | Key Features | Use Case |
|---|---|---|
| Marvin | Advanced customization, annotations, cloud sync | For power users who want detailed control over reading experience |
| KyBook | Supports multiple formats, OPDS catalogs, cloud integration | Users needing multi-format support and online library access |
| Bluefire Reader | DRM support, bookmarks, highlights | Reading DRM-protected ebooks from libraries or stores |
| Adobe Digital Editions | DRM management, syncing | For ebooks with Adobe DRM protection |
Choosing the right app depends on your specific needs, such as DRM support or advanced reading features.

Step-by-step guide to open EPUB file on iPhone
Step 1: Locate the EPUB file on your iPhone
Before opening an EPUB file, you need to find where it is stored. It could be in your Mail app, Files app, or downloaded from Safari or a cloud service.
Open the Files app or Mail and navigate to the folder or email containing the EPUB file.
Step 2: Tap the EPUB file to preview it
Tap the EPUB file to open a preview. The iPhone will attempt to display the file, but it may not fully render without a reader app.
Step 3: Use the Share icon to open with Apple Books
While previewing the EPUB file, tap the Share icon (a square with an upward arrow) at the bottom or top of the screen.
This opens the share sheet with app options.
Step 4: Select "Copy to Books" or "Open in Books"
From the share sheet, scroll through the app icons and tap "Copy to Books" or "Open in Books." This imports the EPUB file into Apple Books.
Step 5: Read the EPUB file in Apple Books
Apple Books will launch and open the EPUB file. You can now read, bookmark, highlight, and annotate the ebook.

If you use iCloud and Apple Books on multiple devices, ensure iCloud Drive is enabled for Books in Settings. This syncs your EPUB files and reading progress across iPhone, iPad, and Mac.
