Best MOBI Readers for Windows

Posted by on .

Mobi format was invented by the French company Mobipocket and was originally used as an ebook format for their MobiPocket Reader application. The company was aquired by Amazon in 2005 and since then mobi format has been used in Amazon's Kindle. The Amazon's eBook formats, including .azw, .azw1, and .azw3, use the MOBI format but incorporate a proprietary DRM scheme to prevent unauthorized users from viewing or copying an eBook that is contained in the MOBI file. Mobi files usually have .mobi extension, or they may have .prc or .pdb extension as the format was originally designed for Palm Pilot PDAs. The extension can be changed by the user to either of the accepted forms.


MOBI files support things like bookmarking, JavaScript, frames, and adding notes and corrections. They are supported by various eReaders, tablets, PDAs, and desktop computer applications. If you own a Kindle device you can read the mobi files on the Kindle device with perfect reading experience. But have you wondered what programs can open mobi files on your computer if you don’t have a Kindle device or other supported eReaders? Luckily you’ll be introduced the 4 best MOBI readers for Windows in this article. You can enjoy the best possible mobi reading effect with these programs installed on your PC.

Supplementary Remarks

Besides the top 4 Mobi Readers for Windows I mentioned above, there’re other less superior programs can read mobi files on PC such as Calibre, FBReader, Icecream Ebook Reader, ect.

Calibre is more than an ebook reader, it’s a complete management software. You can read ebooks, convert ebook formats and organize your library with Calibre. It even has an inbuilt portal from where you can download DRM free and DRM restricted ebooks distributed by a variety of different ebook online stores. However, for the sole purpose of reading mobi files, Calibre seems a little bloated. Compared with the above 3 Mobi Readers, Calibre opens mobi files comparatively slow. It performs sluggishly or even crashes when opening a large size of mobi file.

FBReader is great on Android but is barely satisfactory on Windows. It’s a lightweight, smooth, and no-frills program, but it has a prominent flaw for the Windows version: it crashes when you browse your SD card, and it doesn’t work with OneDrive. FBReader for Windows has not been maintained by the developer or publisher any more.

Icecream Ebook Reader is actually a decent Windows based ebook reader. It enables you to read ebooks in EPUB, MOBI, FB2, PDF and other popular formats. It also features the ability to turn pages, use bookmarks, add notes, translate text, search your library, track reading progress and more. However, the free version allows only 10 ebooks inside its digital library, and you cannot edit the metadata about them.

P.S. Please note that only DRM free files can be supported by these apps. If the MOBI files contain DRM restriction, you need to strip DRM from the MOBI files before reading them on these apps. If you want to read DRM protected MOBI files with these tools, I highly recommend you to install the best eBook DRM removal and converter – Epubor Ultimate!
