Trying to read your EPUB books on a Kindle? You’re not alone. In 2025, Kindle devices have become a lot more flexible—but there are still some quirks when working with EPUB files.
This guide will walk you through the easiest ways to transfer EPUB files to your Kindle, using either Amazon’s official tools or third-party software like Calibre. Whether you’re moving over your digital library or just received an EPUB from a class or colleague, here’s how to get it onto your Kindle.
📚 What File Formats Does Kindle Support in 2025?
As of 2025, Kindle now accepts EPUB files, but there’s a catch: they’re converted during transfer.
Supported formats include:
- EPUB (converted via Send to Kindle)
- MOBI (legacy, no longer recommended)
- AZW3 / KFX (native Amazon formats)
- DOC/DOCX, TXT
⚠️ Note: You can’t just drag-and-drop EPUB files to Kindle via USB—they won’t open. You must use Send to Kindle or convert via a tool like Calibre.
✅ Method 1: Send to Kindle (Recommended)
Amazon’s Send to Kindle tool is the easiest and most reliable method.
🔹 Option A: Send via Email
Every Kindle device has a unique email address. Here’s how to use it:
- Go to Amazon > Manage Your Content & Devices > Preferences
- Scroll to Personal Document Settings
- Find your Kindle email address (e.g., yourname@kindle.com)
- Add your personal email to the Approved Sender List
- Send the EPUB as an attachment to your Kindle address
🧠 Tip: Subject line can be blank. No need to write anything—just attach and send.
🔹 Option B: Use the “Send to Kindle” Web Tool
- Go to https://www.amazon.com/sendtokindle
- Sign in with your Amazon account
- Upload the EPUB file
- Choose your Kindle device
