Ebook File Details: EPUB, Kindle EPUB and PDF

Accepted File Types

When you upload your ebook to BookFunnel, you can upload between one and three ebook files per book: Generic EPUB, Kindle EPUB, and PDF.

Uploading your ebook files is as simple as dragging-and-dropping them onto your book on the BookFunnel dashboard.

GENERIC EPUB

Any non-Kindle EPUB you upload to BookFunnel will become your “Generic EPUB”. Your generic EPUB will be distributed to any non-Kindle app, including Apple Books, Kobo, NOOK, and Play Books.

If you use Vellum to create your books, please export a Generic EPUB. Store-specific EPUBs can be broken when opened in the wrong reading app.

KINDLE EPUB

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). BookFunnel can distribute a special Kindle EPUB file for Kindle readers. Learn more about Kindle EPUBs.

PDF

PDF files are great for things like worksheets, coloring books, and graphic novels, and can be used for ebook files as well. PDF-only files are not ideal for ebook reading, as many people now read on their mobile phones. PDF files, unlike ebook files, don’t allow font or text size adjustment.

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!).

Maximum File Size

The largest file you can upload to an author account is 300 MB*.

Please note: many readers cannot accept email attachments larger than 20 MB, so your file should be smaller than that if possible. If the file is too large, readers cannot send your book to their Send To Kindle @kindle account.
