Our ebook packages include three file formats, the PDF, a Kindle file and an epub file.
PDF files can be read on all computers and devices, but if you have an Apple device that doesn't have a PDF reader, you'll need to install a free one. PDF files match the print book layout — they look a little better, but in ereaders, the formats below will probably be better because you can adjust the font size and use your other reader app tools.
Epub files can be read with iBooks and most other ereaders or ereading apps on other tablets, mobile phones or devices.
Mobi or prc are the files your Kindle or Kindle app will be looking for.
