What is the MOBI format?
MOBI is a file format developed by Mobipocket, a French company Amazon acquired in 2005. The .mobi file extension was used by the Mobipocket Reader desktop app and early Kindle devices, and it became one of the most common ebook file types of the 2000s. A MOBI file can hold text, chapters, images, and bookmarks, but it lacks modern typography features. Compared with newer formats, the MOBI format also caps file size and styling, which is why Amazon retired it in favor of KF8/AZW3 — and why you should convert MOBI files to EPUB to keep older books readable on modern eReaders and mobile phones. Most online converters handle this in one click.
