Kindle Update 5.14.1 Adds Navigation Options while Reading

Amazon has a new, free software update available for your Kindle, including Kindle Paperwhite (7th/10th Generation), Kindle (8th/10th Generation), and Kindle Oasis (8th/9th/10th Generation). As usual, this update automatically downloads and installs on your Kindle when connected wirelessly; however, you can also manually download the software and transfer the update to your device via USB cable. 

Here's what's new:

Navigation options while reading: You can now navigate more easily within a book that has footnotes, endnotes, bookmarks, notes/highlights, or links.

Performance improvements, bug fixes, and other general enhancements.

The main change about the new Kindle firmware update is that it comes with a new “Back to Page” option on the lower-left corner of the screen when you are navigating throughout a book.

Whenever you use the table of contents or jump to a different page, the “Back to Page” option will show up on the bottom of the page forever until you click on the “Stay Here” button to get rid of the dialog box, which is kind of stupid and annoying.

How to Convert Audible MP4 Files to MP3

Recently, a few users reported that now the Audible books downloaded from the audible.com site are in MP4 format instead of AAX. As we all know, the existing Audible Converters in the market only support converting Audible AAX or AA files. So how can we convert Audible MP4 to MP3? Is there any solution for the MP4 files?

After researching and testing this issue, I found the solution finally and here I would like to share it with you.

As for now, the Audible MP4 files only appear in the latest version of Firefox that is 93.0, but for both Windows and Mac - no matter what the computer OS is. 

How to Convert Audible MP4 Files to MP3?

Although the file downloaded saves as .mp4 but is really an aax file in disguise. Nothing is changed in the inner structure, but only the file extension. So here we got it resolved. 

Step 1. Right-click your Audible MP4 file and Select "rename".

Step 2. The filename is automatically selected. You need to click and drag over to the extension. Change the .mp4 extension to .aax.

Step 3. Once the mp4 file extension is changed to aax, you can start to convert the AAX files to MP3 with Epubor Audible Converter. Download and install the program, then just add your AAX files to the main interface, click the button "Convert to MP3". Once the process is finished, you will get your Audible files in MP3 format.

Print Google Play Books to PDF - The Easiest Way

Are you trying to print your ebooks from Google Play Books to paper books but don't know how?  As an online ebook store, Google Play Books provides a large number of titles for us to choose from. It offers an online built-in reader and reading apps for Android/iOS. However, the digital devices could easily get eye strained. That's the reason why a lot of people would love to print them out to read in papers. Here in this post, you will get the easiest way to convert your Google Play Books to PDF and then print them out. 

Step 1. Download Google Play Books to your computer.

First, open a browser on your computer and go to your Google Play Books library. Find "My Books", select a book, click the three-dots button in the corner, and then "Export".

On the pop-up window, you'll be asked to "Export ACSM for EPUB" or "Export ACSM for PDF". Just choose "Export ACSM for PDF".

Note: You will get an .acsm file when it's downloaded. It's not a real ebook file. To convert it to PDF, you will need to open the ACSM with Adobe Digital Editions. 

Step 2. Open ACSM Google Play Books with Adobe Digital Editions.

Now download and install Adobe Digital Editions (ADE) to your computer. It's available for both Windows and Mac. The first time you open the program, you need to authorize it with an Adobe ID. If you're not asked, you can click "Help" >> "Authorize Computer" to get it authorized. If you don't have an Adobe account, just create a new one.

Then you should open the ACSM file with ADE. Just right-click it and then choose "Open with Adobe Digital Editions", or simply drag and drop the file to the interface of ADE.

You have to wait a few seconds for the book downloaded completely. After that, you will see your Google Play books are automatically opened.

Note: Once the Google ACSM files are added to Adobe Digital Editions, they turn to PDF (or EPUB) format. However, they cannot be printed by Adobe Digital Editions and you will find the "Print" option is greyed out. The reason is that the books are still protected by DRM. It's a password scheme. To successfully print your DRM-protected Google Play Books, you must remove the DRM protection by Epubor Ultimate. Continue reading, you will be guided through the whole process.

Step 3. Remove DRM from Google Play Books with Epubor Ultimate. 

Download and install Epubor Ultimate. It's the best eBook DRM removal & eBook converter for Google Play Books. 

Download Epubor Ultimate for Free
 

Run Epubor Ultimate. All your (ACSM) Google Play Books opened with Adobe Digital Editions are automatically detected and displayed under the "Adobe" tab. Now just drag and drop your books from the left side to the right column. You will find the books are automatically decrypted. It means the DRM is successfully removed. 

Then please continue to click the button “Convert to PDF” if your original Google Play Books are in epub format. Once the conversion is finished, just click the “Succeeded” word to find your converted PDF Google Play Books.

Step 4. Print Google Play Books to pages.

Once you have converted your Google Play Books to DRM-free PDF, all that's left to do is to print the PDF file to pages. There are many PDF readers that support the print function. 

Here I just open the PDF file with Microsoft Edge browser on my Windows 10. If you are using Mac, you can open the PDF files with the native software "Preview". Click on the "Print" icon at the top menu bar, then choose the pages that you would like to print and hit the "Print" button.

That’s all for printing Google Play Books to PDF and pages. It's rather easy, right? Don't hesitate to get Epubor Ultimate in handy! The good news is that now you can get Epubor Ultimate lifetime license with 10% OFF!

With Amazon Kids+, hundreds of Audible books are available, including classics like The Secret Garden and Peter Pan; and Audible Originals like Interview with the Robot and The Mystwick School of Musicraft.

Now more than ever, it’s delightful to get lost in millions of books wherever you go.  

Here’s the detailed information regarding new features for Kindle Paperwhite from the Amazon press release: 

1. Next generation Kindle Paperwhite comes with a larger 6.8-inch glare-free display, up to 10 weeks of battery life, adjustable warm light, USB-C charging, and 8 GB of storage—for only $139.99

Version 1.32 or Later Kindle for Mac Does Not Come with Renderer Test File!

Amazon released the latest 1.32 Kindle app for both Windows and Mac. One thing we have noticed that it is that version 1.32 Kindle for Mac does no come with the renderer test file, comparing to the earlier version Kindle for Mac. The biggest effect of lacking the renderer text file is that Kindle users can no longer use the command line to disable KFX format which can not be cracked by current DRM Removal technology. Therefore, the command line will no work for version 1.32 and later Kindle for Mac, which means that you are not able to remove Kindle DRM by running the command line. 

Version 1.31 and lower Kindle for Mac includes the renderer-test file under the MacOS folder: 

Version 1.32 or later Kindle for Mac does not include the renderer-test file under the MacOS folder:

3. Calibre Viewer

Calibre is an open-source suite of ebook software. It's famous for its ebook management functions. Actually, it also offers an ebook reading feature, supporting a large number of ebook formats.

Supported Format: PDF, EPUB.

5. Thorium

Thorium Reader is my favorite EPUB/PDF ebook reader, although it's known to very few people. Thorium Reader is based on a set of open-source projects. So this application is free, with no ads and no leaks of private data. It has abundant features and functions. Personally speaking, this is a perfect tool for heavy readers.
