Adding Ebook Files to Kindle and Kindle App from Your Computer

After downloading a .mobi file, there are three ways to add it to your Kindle library. We recommend first trying to use Amazon's Send to Kindle desktop app. If that doesn't work, you can send files to your Kindle using your email or transfer the file with a USB cord. If you are having trouble using the Prolific Works App to download to your Kindle app, click here.

Send to Kindle App from a Computer

If you are on a computer (Windows or Mac), there is a program you can download called Send to Kindle. It is an official Amazon program that will quickly get mobi and pdf ebook files from your computer to your Amazon Kindle account.

  1. Download the appropriate Send to Kindle for your device. (If you have a pc, download Send to Kindle for PC, if you have a mac, download Send to Kindle for Mac, etc).
  2. When you’ve downloaded the program, find it on your computer (usually you should be able to find it in your “Downloads” folder). This will open an “Installer”. This Installer will guide you through the installation of the Send to Kindle program onto your device. Follow the instructions it gives you.
  3. Once you download and install this program, it will ask you to log in to your Amazon account.
  4. Find the attachment at the top or bottom of the email called “Here is your claimed book!”, and click on the attachment to download the file.
  5. Find the ebook file (.mobi or .pdf only) on your computer where you saved it (when you download a file, it is automatically sent to your “Downloads” folder unless you have picked a different default location for downloads or saved it elsewhere), and drag the file into the Send to Kindle app where it says “Drop files here”.
  6. Put a checkmark next to the device you want to send your file to and click “Send”.
  7. You should see a dialogue box that reads “Upload complete". Give us a few minutes to format and deliver your document. Please ensure your Kindle is connected to the network to receive your document. Select the “OK” button
  8. The book should appear in your Kindle library. If it doesn’t, select “Sync & Check for Items” and check if your book has arrived. This may take a few minutes. If you have a Kindle Fire, the book might be found in the “Docs” section, and the cover may not appear until you have opened the book.

Send From Your Email

If Send to Kindle doesn’t work for you, send files directly to your Kindle email. You'll first need to find your Kindle email address through, and then you'll be able to forward your book file to your Kindle.

Adding an Approved Kindle Email Address

  1. Login to your Amazon account through the Amazon website.
    1. If you live in the United Kingdom, use Amazon's international site.

Transfer with USB

If you are still unable to access your book, here is a step-by-step process on how to transfer documents from a desktop or laptop computer to any device.

  1. Find the attachment at the top or bottom of the email called “Here is your claimed book!”, and click on the attachment to download the file.
  2. When you download a file, it is automatically sent to your “Downloads” folder unless you have picked a different default location for downloads (you may also save it to a particular folder if you choose).
  3. Connect your ereader device (you can also connect iOS and Android devices) with the appropriate USB cable. Plug the USB cable into your computer.
  4. Depending on what kind of Kindle you have, when you plug it in, it should say, “If you want to read or shop on your Kindle while continuing to charge over USB, please keep the USB cable attached, but eject your Kindle from your computer.
  5. Locate the folder for your device under the “My Computer” folder on Windows. On a Mac, your device will show up in the sidebar of any “Finder” window under “Devices”.
  6. You can drag your ebook files directly into the Device folder and the specific documents folder if one is required for your device OR you can copy and paste the file onto the device by right clicking (or ctrl-clicking if you’re using a mac) on the file and selecting “Copy” or “Copy file”, going into the Kindle’s Documents folder, right/ctrl-clicking in the empty space and selecting “Paste” or “Paste Item”.
