e-readers like Kindle have revolutionized the way we consume books and documents. While Kindle primarily supports its proprietary format, MOBI, users often find themselves wanting to transfer PDFs, EPUBs, and other file types to their Kindles for a more diverse reading experience. In this guide, we’ll explore various methods to seamlessly send different file formats to your Kindle, ensuring an optimized and personalized reading experience.

Kindle Supported Formats
First, we need to know what eBook formats you can transfer to Kindle;
- PDF (.PDF)
- Microsoft Word (.DOC, .DOCX)
- HTML (.HTML, .HTM)
- RTF (.RTF)
- Text (.TXT)
- Images (.JPG, .JPEG, .GIF, .PNG, .BMP)
- EPUB (.EPUB)
As you see on the above displayed list MOBI (.MOBI and . AZW) are not listed, which means that they are incompatible with the transfer process. You can always choose to convert the MOBI documents to the acceptable formats to proceed.
How to Send PDFs, EPUB, and More Files to Kindle
In this guide, we will detail 3 ways through which you can send PDFs, EPUB, and more files to Kindle.
1. Send via Kindle Email Address
Amazon offers a convenient service called “Send to Kindle,” allowing users to send documents to their Kindle devices and apps via email. To use this service, simply send an email to your Kindle email address (found in your Kindle settings) with the desired file attached. Amazon will automatically convert the file to a Kindle-compatible format and deliver it to your device.
2. Send via Kindle Web
Use the web version of SendtoKindle to upload documents that are 200 MB or smaller from your device. Follow these steps:
1. Go to the Amazon Send to Kindle website.

2. Drag and drop your files or manually add them.
3. Make sure to activate the ‘Add to Library’ feature to enable downloading this document on any device associated with your account.
4. Then tap on ‘Send’. The new document will be added to your Kindle Library.
3. Send to Kindle via the Kindle App
For this method, you will need the document saved on your mobile phone already.
