EPUB Reflowable is a type of EPUB file that flows to fit the screen size of the reader device. Reflowable content can be reflowed without losing the original pagination and layout of the book.
EPUB Reflowable files are usually smaller in file size than Fixed Layout files because the content is not "locked down" into a specific layout. This makes Reflowable files more flexible and adaptable to different screen sizes, but it also means that the text may not always look its best on every device.
If you are looking for an EPUB file that will look great on all devices and is easy to create, go with a Fixed Layout file. If you need a smaller file size or more flexibility in how your content looks on different devices, go with a Reflowable file.
