What is an EPUB File

EPUB is a popular digital eBook format used for storing and reading books, magazines, and other written content on electronic devices.
The file type is called EPUB, which is short for Electronic Publication. The beauty of EPUB is that the text and images will scale to fit the different sizes of screens.
Unlike PDF files, EPUB files offer the flexibility of changing the font size, style, and layout, which makes them the best choice for use in eReaders and other portable devices. Due to this flexibility and compatibility, the EPUB format is used in most eBook applications and platforms.

Common Issues When Opening EPUB Files and How to Fix Them
There are instances where you may experience some errors while opening an EPUB file. Some common problems that occur while reading EPUB files, along with their solutions, are as follows:
EPUB File Won’t Open: This issue is normally due to the file being corrupted or the reader app not fully supporting the EPUB file format. The file should be opened using a different reader app, or the file should be re-downloaded from a trusted source.
EPUB Shows Formatting or Layout Issues: If text appears to be broken or images are not loading correctly, this does not necessarily mean that the EPUB file is faulty, merely that it is not fully compatible with the current application being used to open the file. The application itself may need updating, or the file needs to be opened within a different application, such as Calibre.”
EPUB File Opens as ZIP or Unknown Format: EPUB files are actually ZIP archives. If your device recognizes the file as a ZIP archive, ensure the file extension is .epub and use an EPUB reader instead of a file extractor.
EPUB Not Opening on Mobile Devices: This is often due to missing reader applications or denied storage permissions on an Android device. You should install a trusted EPUB reader application and allow it access to device storage.
DRM-Protected EPUB Files: Some EPUB files are DRM-protected and can be opened using particular apps, which are connected to the original store where the purchase was made. Use the official app, which is associated with the purchase of the file.
