What is a MOBI file?
MOBI is a legacy eBook format developed by Mobipocket, later acquired by Amazon. It supports complex content like bookmarks, annotations, and DRM, and was used extensively on early Kindle devices.
Although Amazon has transitioned to newer formats like AZW3 and KFX, MOBI files are still supported on older Kindles and widely used for distribution due to their compatibility with many reading apps.
How to open MOBI files
MOBI files can be opened using Amazon Kindle devices, Calibre, and Mobipocket Reader. Many third-party eReader apps on Android and Windows also support MOBI.
If needed, use AnyConv to convert MOBI to EPUB, AZW3, or PDF for greater compatibility.
