MOBI is an eBook format originally developed by Mobipocket and later acquired by Amazon. It supports bookmarks, notes, and reflowable text. While largely replaced by AZW and EPUB, MOBI files are still readable on many Kindle devices and apps.
AZW3, also known as Kindle Format 8, is a newer eBook format from Amazon. It supports HTML5 and CSS styling, offering enhanced layout and formatting options for Kindle books. AZW3 files can contain both older MOBI content and newer EPUB-like structures for broader compatibility.
Convert your .mobi files to .azw3 right in your browser — no downloads, no installs. Everything happens securely in the cloud.
We never store your files permanently. Only you can access them, and they’re automatically deleted from our servers within 2 hours.
Turn your MOBI files into AZW3 in just a couple of clicks. No registration, no limits — and it’s 100% free.
