* If you are subscribed to our Mid-List plan (or higher), you can request a limit of 100 MB. If it the file is too large, readers cannot send your book to their Send To Kindle account.

Please note: many readers cannot accept email attachments larger than 10 MB, so your file should be smaller than that if possible.

The largest file you can upload to an author account is 30 MB*. You’re not required to provide a PDF with your ebook, but some readers will appreciate it, especially if they read on their computer or like to print out books for reading (yes, really!). PDF files, unlike ebook files, don’t allow font or text size adjustment.

PDF-only files are not ideal for ebook reading, as many people now read on their mobile phones. PDF files are great for things like worksheets, coloring books, and graphic novels, and can be used for ebook files as well. If you do not upload a MOBI, BookFunnel will automatically create one from your Kindle EPUB or Generic EPUB.

Kindle ereaders like the Paperwhite, Voyage, Oasis, Touch.

BookFunnel will offer MOBIs for direct download for readers on these devices until Amazon completes their transition to EPUB: LEGACY MOBIĪmazon has deprecated MOBIs, but many readers are on legacy Kindles that can’t open an EPUB file. To improve these conversions, BookFunnel can distribute a special Kindle EPUB file for Kindle readers. Sometimes the converted file looks very different, especially in the Kindle app on iPhones and iPads. When you send an ebook to Send to Kindle, Amazon converts it to their own format and then delivers it to your Kindle (or Kindle app). Store-specific EPUBs can be broken when opened in the wrong reading app. If you use Vellum to create your books, please export a Generic EPUB.

Your generic EPUB will be distributed to any non-Kindle app, including Apple Books, Kobo, NOOK, and Play Books. Screenshot of book details view on the BookFunnel dashboard GENERIC EPUBĪny non-Kindle EPUB you upload to BookFunnel will become your “Generic EPUB”.
