MOBI (Mobipocket) is a widely used ebook format originally developed by French company Mobipocket SA and later acquired by Amazon. This versatile format offers features like bookmarks, annotations, and variable font sizes while maintaining relatively small file sizes through efficient compression.
MOBI files remain one of the primary formats for Amazon Kindle devices, though Amazon has been transitioning to newer formats like AZW3. The format supports basic formatting, images, and a table of contents, making it suitable for most fiction and text-based non-fiction. Its widespread compatibility extends beyond Amazon's ecosystem to numerous ebook readers and applications. Supported extension is .mobi.
How to open MOBI?
MOBI files can be opened on all Amazon Kindle devices and through the Kindle app available for Windows, Mac, iOS, and Android. This ensures broad compatibility across Amazon's reading ecosystem with full support for all the format's features.
Beyond Amazon's applications, numerous third-party readers support MOBI files, including Calibre, FBReader, and Moon+ Reader. Most e-readers and reading apps offer at least basic MOBI compatibility, making it one of the most accessible ebook formats available today.
