Like EPUB, it is supported by almost all modern e-readers specifically by mobile devices with low bandwidth. The format is an enhancement to the old OEB (Open Ebook Format) format and was used as the proprietary format for Mobipocket Reader. After August 18, please use the EPUB format for viewing on Kindle apps and devices. The MOBI file format is one of the most widely used ebook file formats. Please visit your account and download any MOBI files you wish to retain, before August 18.

This change does not mean any loss in content from your purchase, as the EPUB file already included with your purchase still contains all the same content, and may be used on the same devices and apps as the MOBI format was. Purchases of future multi-format eBook files on after August 18 will include the EPUB and PDF formats, but will no longer include MOBI. However, the downloadable multi-format eBook files available on your Microsoft Press Store account will no longer include the MOBI format those links will be removed on August 18, 2022.

I highly recommend SumatraPDF or MuPDF if you're after something a bit more. You may or may not need an add-on or extension to do it, but it's pretty handy to have one open automatically when you click a PDF link online. Most web browsers, like both Chrome and Firefox, can open PDFs themselves. It's completely fine to use, but I find it to be a somewhat bloated program with lots of features that you may never need or want to use. Adobe created the PDF standard and its program is certainly the most popular free PDF reader out there. Most people head right to Adobe Acrobat Reader when they need to open a PDF. PDF files always look identical on any device or operating system. The reason PDF is so widely popular is that it can preserve original document formatting. The Portable Document Format (PDF) is a universal file format that comprises characteristics of both text documents and graphic images which makes it one of the most commonly used file types today.
