    EPUB (Electronic Publication) is a widely used open standard for digital e-books and publications. EPUB files are designed to be reflowable, meaning the content adapts to different screen sizes and orientations, making it suitable for a variety of devices including e-readers, smartphones, and tablets.

    EPUB supports text, images, and multimedia, and is commonly used for distributing e-books in formats that are easy to read on a wide range of devices. It’s supported by most e-book readers except Amazon Kindle, which uses its own proprietary formats.

    How to open EPUB?

    EPUB files can be opened with a variety of e-reader applications, such as Adobe Digital Editions, Calibre, and Apple Books.

    On Windows, Calibre is a popular tool for reading and managing EPUB files, while macOS users can use Apple Books or other third-party apps like Calibre or BookReader.
