Epub To Kindle Converter Mac

Posted on  by admin

I started off reading eBooks from the Amazon Kindle store. As time has progressed, I’ve found myself using my physical Kindle less and less. Partly because I forget to charge it, and partly because I can never get the lighting in my favorite reading locations quite right. And at night? Forget about it.

Epubor EPUB To Kindle Converterc allows you to convert epub books to kindle/mobi with best output quality and fastest conversion speed. Mac epub to kindle converter is a very professional software. PDF/ePUB to Kindle Tool. PDF/ePUB to Kindle Tool is a powerful application designed to enable you to convert pdf to kindle mobi format, and epub (also HTML,TXT) to kindle mobi format. It’s more efficient when you use Kindle to get e-book resource on the internet. To convert PDF to Kindle, click the output format dropdown list next to Advanced Settings and select to EPUB. Click Convert in the lower right corner, select a location on your Mac to keep the output Kindle ebooks, and click Save. The conversion will start immediately.

So I’ve converted all of my Kindle purchases to ePubs for use in iBooks. I could use the Kindle app for iOS but I’ve found iBooks to be faster at syncing read position, and it feels a lot more natural to use.

Since I went through the effort of converting all of my Kindle documents, I figured I’d write a mini guide to getting it done. I’m specifically focusing on the Mac since that’s all I know; other users will have to venture elsewhere.

Setting up Calibre

Calibre is a Java application which is an eBook management suite. It’s a bit ugly but it does what it says and works well. Since the Kindle’s eBooks are encrypted, we need to install a decryption plugin to do the heavy lifting there.

  1. Download and install Calibre.
  2. Download and decompress the DeDRM archive.
  3. Open Calibre’s preferences (⌘,).
  4. Go to “Plugins”.
  5. Click “Load plugin from file”.
  6. Choose the K4MobileDeDRM plugin’s zip file (zip within the main zip; don’t extract).

The encryption used on Kindle books is fairly basic. The decryption key is a product of the serial number for your device, so it’s not difficult to determine.​

Getting eBooks

The DeDRM scripts work by understanding Kindle for Mac’s settings files, so to get the eBooks we need use the application. There are scripts to do conversions directly from Kindle hardware’s eBooks, but it’s more effort.

  1. Download Kindle for Mac.
  2. Register it with your account.
  3. Download all of your eBooks (open them from the “Archived Items”).

Converting eBooks

Kindle eBooks are in the MobiPocket format. However, iBooks requires ePub, so we need to both decrypt and convert the files. At this point, we’ve got all we need, so we can use Calibre to do the conversion.

  1. Navigate to ~/Library/Application Support/Kindle/My Kindle Content/
  2. Drag all of the .azw files into the Calibre window.
  3. Select the books in the Calibre window which you wish to export.
  4. Click the “Convert books” toolbar item.
  5. Choose “ePub” as the output format in the top-right of the convert window.
  6. Go to the “Page Setup” item in the left list, and configure the conversion as so:
    1. Select “Kindle” as the input profile.
    2. Select “iPad” as the output profile.
  7. Hit the “OK” button to begin the conversion. It may take a while.

If you have any issues at the decryption step, you should delete your~/Library/Application Support/Kindle folder and start again.


You can now “Save to disk” from the toolbar item to save the books which you’ve converted, and import them into iTunes for use in iBooks. Calibre is powerful enough to do many other formats if you want to use other devices as well.

Remember, don’t post any of the unencrypted documents anywhere. Just because the DRM is gone doesn’t mean you’re legally authorized to do so. They’re for your personal use only.

One of the most common questions I get asked when people start making ebooks is “Do I really need to create two separate files? One for Kindle and another for everyone else?” And then they usually ask if it takes twice as long 🙂

This isn’t a silly question. Anyone that looks at the files that publishers provide to readers can see there are two different file formats: .epub and .mobi. But just what is the difference, and why do we need both?

The .mobi format

The .mobi format is specific ebook formate for Kindle devices. There’s a long history of both technological and corporate reasons for it to be the main file format or Kindle readers, but suffice to say you’ll need to make a .mobi file at some point if you want to submit the file to the Amazon’s Kindle store.

Today, the .mobi format is really just a proprietary file type not that different from an ePub. And the good news is that you no longer need to create this file from scratch. Kindle has created a suite of tools to convert other file formats to the .mobi format. And since you’ve obviously created an ePub—the best ebook format around—we’ll look at how to convert a .epub file to a .mobi file

The Three Best Ways to Convert an ePub to a .mobi File

There are lots of ways to convert an ePub to .mobi, but I’m going to talk about the three best ways to do it. All three use Amazon’s tools, so you can be assured that they are how Amazon wants you to convert them. We’ll start with the easiest way that anyone can use, and move to ways that more professional and technically-minded ebook creators can use.

The KDP uploader

Arguably the easiest method to use is Amazon’s KDP system. If you just want to create a .mobi file as quickly as possible this is the easiest way. It’s a two-click process (assuming you already have a KDP account), and once the epub is uploaded you are ready to sell your book.

  1. Create a KDP account (if you just want to follow along, you can create a free account to bypass the bank info)
  2. Click “Add a New Title” (upper lefthand corner of the main KDP screen)
  3. (If you want to submit this book to Amazon, fill out #1-4, but I’m going to skip them)
  4. Scroll down to #5: Upload Your Book File
  5. Click “Browse” and select your book
  6. Once the file has finished converting, #6: Preview Your Book will appear
  7. In the bottom box labeled “Downloadable Previewer”

The Kindle Previewer

The KDP upload process is great, but it has one fatal flaw for people that want to create a professional looking ebook: its preview process to ensure the ebook looks great isn’t great, and if you do find issues, you’ll be doing a lot to uploading and downloading of files.

Amazon’s answer to this problem is the Kindle Previewer. It’s an app you can download to a computer to preview what your .mobi file will look like on various Kindle devices, and if you jump back to step #7 above you’ll see Amazon recommends you use it to preview your files. But it also has the added benefit of converting your ebook to .mobi, allowing you to skip the KDP Upload process.

  1. Download the Kindle Previewer app here: http://www.amazon.com/gp/feature.html?docId=1000765261
  2. Open the App
  3. Drag your ePub file onto the Kindle Previewer window
  4. This will create a folder of generated files in the same location as the ePub file
  5. Inside that folder (once the process is complete) will be your .mobi file


Lastly I’m going to talk about kindlegen. If you’re not a technical person, you can probably just skip this section 🙂 But if you like/prefer the command line, or are looking for ways to automate a .mobi creation process, please continue along.

The process behind generating .mobi file from ePubs in both the KDP upload and the Kindle previewer is a tool called kindlegen. Amazon offers to tool in a java format to allow developers to use it themselves if they so desire. When you run kindlegen form the command line you’ll also get an output of warnings, errors, and other helpful information about the .mobi file creation.

  1. Download the kindlegen application here: http://www.amazon.com/gp/feature.html?docId=1000765211
  2. Once downloaded, open up Terminal (assuming you’re a Mac user)
  3. move into the unzipped folder: cd path/to/kindlegen
  4. run kindlegen on file: kindlegen path/to/epub/file
  5. kindlegen will create a .mobi file in the same location as the ePub file.

Other convertors

As I mentioned, there are other convertors out there. You could use Calibre, or an online file convertor, or something else you found on the internet—but I wouldn’t recommend them unless you know exactly how they operate. It’s possible that some of them will alter your ePub file before converting it to .mobi, or they use an outdate version of kindlegen and don’t tell you about it. Both of these could lead to a very painful QA process.
