Best FREE PDF to Mobi Converter Online/Downloadable

Posted by on .

PDF is the most commonly used eBook format as it is supported by almost all eBook readers, tablets, and smartphones. However, the PDF is designed to reproduce fixed-layout pages, which means the PDF format is fixed-format and cannot be reflowed. If you intend to print eBooks, the PDF format is a good choice. However, if you plan to read a PDF file on a device with a screen size less than 10 inches, the reading experience will be horrible. If you have ever read a PDF on Kindle, you must know my feelings—scrolling and zooming in and out to read each line. I bet some of you are still suffering from the bad reading experience now, as Kindle is the most popular eReader. Why not convert PDF to Mobi for better reading on Kindle? Mobi, a native Kindle eBook format, is compatible with Kindle devices very well. In this article, I will introduce you to the 3 best online PDF to Mobi converters and top 3 downloadable PDF to Mobi converters.
