What is a MOBI file?

Mobipocket eBook (.mobi)

MOBI is Amazon's legacy eBook format, originally created by Mobipocket and acquired by Amazon for Kindle devices. MOBI supports basic text formatting, images, tables, and bookmarks. While Amazon has transitioned to newer formats (KF8/AZW3), MOBI remains compatible with all Kindle devices and apps. MOBI files are limited compared to EPUB: they don't support video, advanced CSS, or the latest accessibility features. For publishing on Amazon, authors typically upload EPUB or DOCX files, which Amazon converts to its internal format. Converting MOBI to EPUB provides access to a wider range of e-readers and more modern features.
