EPUBs share many of the same accessibility requirements as the web, many of the same techniques (i.e., image descriptions) that apply to web accessibility can be used when authoring accessible EPUBs. EPUB supports reflowable text, making Ebooks in this format accessible: the reader can change the font size, and the book will reorganize itself to fit the device screen.
Because of their widespread use, more hardware eReaders support EPUB files than any other eBook file format. EPUB file use many different ereaders and free software such as Calibre or Stanza Desktop. Kindle readers do not use EPUB but is possible to convert to MOBI files using Calibre.
