Working with file formats: MOBI, EPUB and AZW3
Understanding the differences between e-book formats is crucial for a comfortable reading experience. For a long time, Amazon's primary standard was the MOBI, but in recent years the company has introduced support for more modern containers. Choosing the wrong format can result in the book opening, but the dictionary, chapter navigation, or font changes not working.
Format EPUB EPUB is a universal industry standard. Previously, Kindle devices couldn't read it directly, requiring conversion. However, new firmware versions and the Send to Kindle service now automatically convert EPUB to Amazon's native format upon upload. This significantly simplifies user experience, as most free libraries distribute books in EPUB format.
Format AZW3 (Kindle Format 8) is a more advanced successor to MOBI. It supports complex formatting, embedded fonts, and improved typography. If you have a choice between MOBI and AZW3 for manual loading, always choose the latter. It provides better page-turning performance.
Below is a table comparing the main features of the formats supported by Kindle:
| Format | Dictionary support | Complex formatting | Automatic conversion |
|---|---|---|---|
| MOBI | Yes | Limited | No (native) |
| EPUB | Yes (after conversion) | High | Yes (via Send to Kindle) |
| AZW3 | Yes | High | No (native) |
| No | The original is preserved | No |
It is worth noting that the format PDF is also supported, but the reading experience on 6-inch screens is often unsatisfactory due to the lack of responsive text. Text doesn't wrap, and you have to constantly resize the page. For PDFs, it's best to use the [unrelated] mode. PDF Reflow, if it is available in your firmware version, or convert the file to EPUB before sending.
Why is MOBI becoming a thing of the past?
The MOBI format was developed a long time ago and doesn't support modern features like changing font weight or complex table layouts. Amazon is gradually phasing it out in favor of EPUB and AZW3.
Using cloud storage and third-party applications
If you don't want or can't use email to transfer books, cloud storage is a great alternative. Many modern e-readers, especially models Kindle Paperwhite and above have a built-in web browser Experience (formerly Experimental Browser). Although it's primarily designed for purchasing books and searching Wikipedia, it can be used to download files.
You can upload the book to the cloud, for example, Google Drive, Dropbox or Yandex.DiskThen, using the Kindle browser, follow the direct link to the file and download it. However, this method has its limitations: the Kindle browser is slow, and downloading large files can take a long time or be interrupted.
A more reliable method for advanced users is to use specialized converter apps on your smartphone. Apps like Send to Kindle (official from Amazon) allows you to select a file from your phone's memory and send it to the device. It's faster than email and allows you to visually monitor the process.
- 📱 Install the Send to Kindle app on iOS or Android.
- 🔗 Log in to the same account as your e-reader.
- 📂 Select the book file in your phone's file manager.
- 🚀 Click the send button and wait for confirmation.

DeDRM in conjunction with Caliber, which is a more complex scenario).
☑️ Check before sending
Troubleshooting and fixing synchronization errors
Even with proper settings, situations may arise where a book doesn't reach the device. Most often, the problem lies in the file size or format. The limit for one document sent via Send to Kindle is 50 MBIf your book contains a lot of illustrations or is a technical book with graphics, the file may be too large.
In this case, you'll need to compress the book or split it into sections. You can use image compression programs or online services. Another common error is region mismatch. The Amazon account linked to the device and the account sending the book must be compatible (although in most cases, the device's region doesn't affect the receipt of personal documents).
If the Wi-Fi indicator is blinking but there is no connection, try restarting your device. To do this, press and hold the power button on 40 secondsThis will force a system reboot and reset the network adapters, which often resolves the issue of a frozen connection.
Another consideration is server response time. Sometimes it can take up to 15-20 minutes for an email containing a book to reach your device. Don't rush to resend the file, as this could create duplicates in your library. Check your Kindle's spam folder if the file still hasn't arrived.
Organizing your personal library and managing files
Once you've learned how to download books for free, the question of organization arises. Thousands of files can turn your library into chaos. Fortunately, Kindle lets you create collections. You can group books by author, genre, or read status. This can be done directly on the device or through the web-based content management interface.

This will speed up searching and make browsing the library more enjoyable, especially if you have more than 100 books installed.
Don't forget to regularly delete your e-books from your device if you're running low on space, although Amazon cloud storage allows you to keep an archive of books in the cloud and download them as needed. Deleting a book from your device doesn't permanently delete it from your account—you can always download it again for free.
