In certain situations, you may encounter problems with MOBI files, so after many (many many) hours of research and experimentation, I wanted to explain, as best I can, what’s going on and what solutions or workarounds are possible. Although Amazon has largely moved on to newer (but still proprietary) file formats, MOBI files remain an industry standard and are important for backward compatibility with older devices. MOBI files are designed for Amazon’s Kindle, which is to say both physical Kindle devices (such as the Kindle Paperwhite or the Kindle Fire) and the Kindle app, available for Mac, Windows, iOS/iPadOS, and Android. Our Device Advice page includes some thoughts on why you might choose one format over another. When you order a book from us, you can download any or all of these formats, as you prefer. Take Control books were originally distributed only in PDF format, but in 2010 we added EPUB and Mobipocket (or MOBI) formats too. But for new downloads, always use EPUB format instead. If you already have MOBI versions of Take Control books on your Kindle, you can leave them there and they’ll continue to work indefinitely. Therefore all of what follows is outdated, and we’re leaving it here for purely historical reasons. As a result, MOBI files are no longer needed or useful, and we no longer distribute them. On December 22, 2022, Amazon finally updated the Send to Kindle apps for Mac and PC to version 1.1.1.254, which adds EPUB support. Important Update: On May 2, 2022, Amazon announced EPUB support for Kindle, which will also mean discontinuation of support for MOBI.
