S,o you bought a new e-book from a platform like Humble Bundle or other online stores.

And, now you want to transfer it to your Amazon Kindle. Fret not, I got you πŸ˜‰

Kindle allows you to sideload books and there are two popular ways to do so. Either use Calibre or send the book to your Kindle mail.

πŸ’‘
It is easier to send ebooks to Kindle via email.

You can find your Kindle email by going to Settings β†’ All Settings β†’ My Account β†’ Send-to-Kindle Email.

Once done, compose an email using your regular email account. Attach the ebook to the email and send it to your Kindle email address.

But, the book must be in a supported format like Mobi or PDF.

Here, we focus on Calibre, as it allows you to configure the book by letting you configure the cover, formatting, and even change a file format to supported ones.

Now, let me highlight the steps you need to follow to transfer any e-book to Kindle using Calibre. If you do not have it installed, follow our guide here to set it up first:

Install the Latest Calibre on Ubuntu
Calibre is a free and open source e-book software. Here’s how you can install it on Ubuntu Linux.

Transfer any eBook to Kindle using Calibre

When you get an eBook from third-party platforms over Amazon Marketplace, you may have to change the file format to make it work on Kindle. For example, most books outside are available in EPUB format, which is supported by other e-readers but not Kindle.

So it is essential to know the file formats first and based on that you can decide if the book you intend to transfer requires the conversion to another format or not.

Step 0: Know the file format

Kindle supports various eBook formats, but for the most part, you'll be dealing with the following four:

  • ePub (not supported by Kindle and needs to be converted to supported ones)
  • MOBI
  • azw3
  • PDF

If the file you want to transfer to Kindle is MOBI, azw3, or PDF, you can directly use it without conversion.

But if you have an EPUB file, then you'd need to convert it to MOBI or azw3.

Here's how to do that:

Step 1: Import a book to Calibre

To import a book to Calibre, first, launch the Calibre software and click on Add books the button, and it will open the file manager where you choose books to add:

Choose books to add in Calibre

Soon, you will see the titles in your Calibre program:

Step 2: Convert eBook to supported file format

If the book you want to send to Kindle is not supported (probably an ePub format), then you can refer to this section where I'll show you how to convert that to a supported file format.

You can identify the file format by selecting an eBook from Calibre and on the right-hand side, you will find Formats where the book format is mentioned:

Find the ebook file format in Calibre

To convert the eBook(s), first select one or more unsupported eBooks and hit the Convert books option:

Select books that needs to be converted

Now, go to Page setup, choose your Kindle model from the Output profile, select MOBI in output format and finally hit the OK button:

Conver Kindle books

Once finished, you will see the converted file format along with the previous file format:

Step 3: Send eBook(s) to Kindle

To send eBooks to your Kindle device, first, plug in your Kindle device to your system and Calibre will detect the device showing a Kindle icon on the top bar.

Now, select one or more eBooks and hit the Send to device button:
