Convert MOBI to EPUB.
Convert MOBI to the open EPUB standard for any modern e-reader. Text and chapter structure preserved.
Free a Kindle book to read anywhere
EPUB is the open ebook standard that virtually every reader speaks — Kobo, Nook, Apple Books, Google Play Books and the reading apps on your phone. MOBI is the old Amazon-only format. Converting MOBI to EPUB lets a book leave the Kindle world and open on whatever you actually read on.
What carries over
Calibre preserves the text, chapter structure, table of contents and metadata, and because EPUB is reflowable the book will resize and rewrap comfortably on any screen.
A note on DRM
Many books bought from the Kindle Store are DRM-protected. This converts DRM-free MOBI files only — your own documents, public-domain titles, or anything without copy protection. It won't unlock a DRM'd purchase.

Free and open-source engine (Calibre)
MOBI to EPUB
This re-flows the book into EPUB, carrying chapters, the table of contents and images. Reflowable ebook formats adapt to the reader's screen and font size. Heavy fixed layouts (comics, textbooks) convert less cleanly.
