― Stephen Fry

PDF files are supported by all Amazon Kindle apps and e-readers. Your PDF files can be uploaded to a Kindle.

This method requires you to adjust the document's size to fit it properly on the screen, which is inconvenient.

As a result, you can use PDF to Kindle converters to easily convert PDF to Kindle formar, allowing you to read PDF eBooks on the go.

Here is what we will cover:

How to Upload PDF to Kindle Directly

If you have a PDF already, there's no need to convert PDF to Kindle format, because the device can already read this format. You only need to upload it, so follow our guide below.

Upload PDF file to Kindle Via USB

USB is a standard for connecting and communicating between computers and other devices. It is a type of computer interface technology. You can upload PDF files to Kindle using a USB data cable.

  • On your computer, locate the PDF file you need to upload to your kindle.
  • Go to "Kindle" > "Documents" and open the folder. Copy the PDF files to the Kindle drive's "documents" folder.
  • Disconnect your Kindle from the computer and eject it. Click the "Safely remove hardware" icon and select "Eject Amazon Kindle" to disconnect your Kindle from the computer. The PDF e-Book can then be read on the Kindle.

Send to Kindle by Email

Many people will download free PDF e-Books from the Internet, but doing so necessitates using a USB data cable to transfer the e-Books to the Kindle, which is more difficult.

Each Kindle includes its own email address. If you want to read a PDF e-Book on your Kindle, the simplest way to do so is to send it to your Kindle via email. So, how do we quickly and easily send PDF e-Books to Kindle? To enable email on your Kindle, follow these steps:

  • Locate your Kindle's address. Go to the Amazon website and sign in. To find the e-mail address of your Kindle device, go to the "Manage Your Kindle" page and look under "Manage Your Devices." Select the appropriate Kindle device. A @ email address will appear in the pop-up window. By clicking the "Edit" button, you can change it.
  • Log in to your email program or service, such as Outlook or Gmail. Send an email with a PDF attachment to this email. Remember to include the word "Convert" in the subject line and to attach the PDF e-Books you want to read.

  • Once we've sent the email, Amazon will convert the PDF file to a size that your Kindle can handle. We only need to wait a few minutes for the Kindle connected to the Internet to automatically update and download the e-Books, or we can manually update the e-Books list by clicking "Sync and View Content" in the Kindle.

Understanding the Kindle Format

Kindle devices are designed to work with Amazon's proprietary e-book formats, which include AZW and, in the case of fourth generation and later Kindles, AZW3, also known as KF8, among others.

The following formats are supported by the Kindle device: MOBI, PRC, TXT, TPZ, and Amazon's AZW formats are all supported on the first-generation Kindle.

In addition to the file types supported by the Kindle 1, the Kindle 2 also supports native PDF, AAX, and HTML files.

From the 4th generation onwards, including the Touch, Paperwhite (1st to 5th generations), and all Voyage and Oasis models, AZW, AZW3 and TXT files are supported, as well as unprotected MOBI and PRC formats. HTML, DOC, DOCX, JPEG, GIF, PNG, and BMP files can all be converted to other formats.

Aside from that, the Keyboard and Touch are capable of reading AA, AAX, and MP3 files. The 7th Kindle, as well as all Kindle Paperwhite variants, Voyage, and Oasis, are capable of reading KFX files.

Now that you know which formats are supported by Kindle, you are one step closer to reading PDF files on the device. To put it simply, simply convert PDF files to the most Kindle-friendly format, TXT, in the same way that Amazon and other PDF converters do.


Because most Kindle devices can read PDF files, there's no need to convert them to other Kindle formats before putting them on the device. You can only zoom in or out on a PDF file when reading it in PDF format. You'll need to convert PDF to Kindle format if you need to change the font only.
