Adding large files to Kindle e-reader, Kindle for iOS, Kindle for Android - a complete guide

In the simple guide below, you’ll learn about different ways of sending a large personal document to your Kindle e-reader or application.

The easiest way to add a personal file to the Kindle account is to email it as an attachment to the email address associated with your Kindle device or app.

There is, however, one factor that makes it impossible. It’s the file size limit.

The size limit of the file emailed to Kindle is being caused by two factors:

  • attachment size limit of your email provider – for instance, for Gmail the limit is 25 MB,
  • size limit on the Amazon side – Amazon won’t accept personal files bigger than 50 MB.

There is a growing number of ebooks that are packed with pictures and multimedia, and therefore are much larger than 50 MB. Cookbooks, picture books or graphic novels are making their way to e-readers and book reading apps. And, of course, Kindle Store is not the only source of them.

More and more ebook vendors offer books in mobi – the file format supported by Kindle.

Even if ebook platforms provide the function to send the purchased file to the Kindle automatically, it won’t happen in the case of ebooks exceeding the accepted size of the outgoing email.

How to send large files to the Kindle or Kindle application? Luckily, there is more than one way of doing it. You can pick up the one that suits you most.

For the purpose of clarity, we’ve grouped the guide in three sections:

There is one more thing you have to keep in mind. The 50 MB is the maximum size of the personal file that will be added to your Kindle cloud library.

Kindle cloud library is the archive of all your books you ever purchased in the Kindle Store or sideloaded. The books are available to download to any of the connected Kindle devices or apps and their content can be synced.

Any file larger than 50 MB can be added directly to the Kindle e-reader or Kindle app, but can’t be backed to Kindle cloud library, and therefore you won’t access it from any other device.

There is another way to cope with the problem. The solution is to reduce the size of the file. We won’t deal with it right now, but, in short, you can use Calibre ebook management software to strip images from the file.

If you have questions regarding the solutions we shared, please do not hesitate to ask.

How to add large files to Kindle e-reader

If you want to add the large personal document directly to your Kindle e-reader, you can do it in two ways.

1. Transfer files via USB cable

This solution lets add ebooks that are larger than 50 MB. It’s convenient when you want to add multiple files at once. You can use it both on a PC and Mac computer.

1. Connect your Kindle to the computer

Use the cable that came with your Kindle, to connect the e-reader to the USB port of your computer. The Kindle should be visible as an external disc.

2. Copy the files to the Kindle

Click on a Kindle disc image. Inside, you’ll see the folder named “documents.” Copy the file or files onto it.

2. Use Send to Kindle app on your computer

This solution lets add multiple personal documents to your Kindle account, but you can only send files no bigger than 50 MB.

If you plan to add to your Kindle library a lot of third-party files, the Send to Kindle app is the most convenient way. Besides adding many files at once, it lets you select several Kindle devices or apps, as well as archive the documents in your Kindle cloud library.

1. Open the Send to Kindle app on your computer

If you still don’t have the Send to Kindle app, you can download it from Amazon. It’s available both for PC or Mac computers.

3. Add files to Send to Kindle app

You can add files in three ways:

  • drag and drop files to the Send to Kindle application,
  • use the Print menu in any application that can print,
  • control-click (Mac) or right-click (PC) on the document or documents.

Below, you can see how to add the file to the Send to Kindle app on a Mac computer.

Drag the file anywhere inside the Send to Kindle window. In the bottom part, you’ll find the list of all devices that are connected to your Kindle account. Select your Kindle e-reader.

If you also want the file to be immediately backed up in the Kindle cloud library, check the box “Archive documents in your Kindle Library.”

How to add large files to Kindle for iOS app

If you own iPhone or iPad, you can add the file to Kindle for iOS application in three ways.

1. Use a cloud storage app such as Dropbox

The solution works for files larger than 50 MB. I’ve tested it on a book that is 70 MB. You’ll be adding the books one by one. If you want to add files in bulk, please use two other methods.

I’ll guide you how to use Dropbox, but you can also successfully use Google Drive or any other cloud storage service.

If you don’t have Dropbox, you’ll need to sign up to the service first.

1. Download the book to your PC/Mac computer

If you’ve bought the book in the third-party ebookstore or found the book in one of the sites that offer free public domain ebooks, make sure to download the file in mobi format.

From here, upload the file to your Dropbox account. You can do it via the web browser or the Dropbox desktop application.

2. Use Dropbox app on the iPhone/iPad to open the file

If you don’t have Dropbox app, you can download it from the App Store.

When you open Dropbox, locate the file and tap it (image below, on the left).

Wait a bit until Dropbox processes the file. The message “No Preview Available” will appear. Tap the three-dot icon in the top right corner (image below, middle).

In the drop-down menu, tap “Export” (image below, right).

Adding large file to Kindle iOS using Dropbox app

A sharing menu will open. Tap “Open in…” icon in the lower row (image below, left).

Then, tap “Copy to Kindle” icon in the upper row (image below, right). If you don’t see this icon in the row, tap the “More” icon in the same row, and make sure to enable the Kindle sharing menu feature.

Kindle for iOS app will open and load the file you’ve just added. It may take a while, depending on the size of the document you wanted to sideload to your Kindle for iOS app.

2. Use iTunes app on a computer

This solution also works for files that are larger than 50 MB. You will be able to add multiple files at once.

The guide shows how to connect iPhone or iPad to a Mac computer, but you can also do it on a PC computer, using iTunes for Windows application.

1. Connect your iPad or iPhone to the computer

Use the USB cable to connect your iOS device to the computer. Open iTunes app if it doesn’t start automatically.

When your device successfully connects to the computer, its icon will appear in the top left corner of the iTunes app.

2. Copy the file to the relevant folder in iTunes

To find the folder holding the files from the Kindle for iOS app, click “Apps” in the sidebar on the left (see picture below).

On the right side, you’ll see “Apps” section. Scroll down to reveal “File Sharing” section. Underneath, you’ll find the list of apps. Select Kindle.

To the right, you’ll see the files that rest inside Kindle for iOS app (see image below).

Now, the only thing is to drag the file from the desktop to the field underneath “Kindle Documents” and drop it there (see image below).
