How to open a EPUB file

EPUB files are widely used for eBooks and digital publications, and various software tools cater to different user needs.

Browser-based solutions like Google Play Books offer convenience for reading on-the-go, while built-in applications on devices provide basic functionality for viewing EPUB files.
