Convert MOBI E-book to EPUB Format
Amazon deprecated MOBI for new uploads in 2022 in favor of KPF/AZW3, and the format lacks modern CSS support. Converting to EPUB gives you a key advantage: content reflows dynamically to fit the reader's screen, font choice, and accessibility settings. EPUB is best for publishing reflowable e-books that adapt to any screen size and support accessibility features.
