About EPUB Files
EPUB is the open standard for eBooks, used by Apple Books, Kobo, Google Play Books and most eBook stores except Amazon. Its text reflows to fit any screen size, and readers can change the font and size. Inside, an EPUB is a ZIP archive of HTML pages, CSS styles and images, much like a small website. Books bought from stores may be protected with DRM, which restricts them to the store's apps. Since 2022, Kindle devices accept EPUB files sent through Send to Kindle.

EPUB File Questions
Can I read EPUB on a Kindle?
