On the book's page, use the "Older Kindles" or "Kindles (kf8)" download option
Connect your Kindle to your computer via USB
Copy the file to the "documents" folder on your Kindle
Email to Kindle
Every Kindle has its own email address. You can email files directly to it.
On Amazon: open Menu → Manage Your Content and Devices → Devices tab → select your Kindle and find its email address
On the same page: go to the Preferences tab → scroll down to "Approved Personal Document E-mail List" → add your own email address, so the Kindle can receive emails from you
Email the EPUB3 file as an attachment to your Kindle's address
Kobo
Kobo makes it easy: plug it into your computer, and it shows up as a USB drive you can drag books onto.
Download the EPUB3 file
Connect your Kobo to your computer via USB
Tap “Connect” on your Kobo’s screen
Drag the file into the Kobo drive that appears
Forma, Sage, Elipsa, Elipsa 2E, and Libra Colour also support Dropbox (no cable needed).
On your Kobo, go to Settings > Dropbox and link your account
Save the EPUB3 file to your Dropbox
On your Kobo, tap the Dropbox icon to sync — the book will appear in your library
Nook
Nook works much the same way as Kobo — plug it in and it appears as a drive on your computer.
Download the EPUB3 file on your computer
Connect your Nook via USB
Tap “Connect” on your Nook’s screen
Copy the file to the “My Files” folder on the Nook drive
Older Nooks (Simple Touch, original GlowLight): use the EPUB file instead.
Other E-readers
Using a PocketBook, Boox, or another e-reader? Just download the EPUB3 file — most modern e-readers support it.
Open the file — if there’s a download notification, tap it. Or find and tap it in your Files/Downloads app.
Pick your reader app if Android asks.
Free reading apps include ReadEra and Moon+ Reader.
Kindle app? It can’t open a downloaded EPUB file. Use Send-to-Kindle instead, and the book will appear in your Kindle app.
Google Play Books is often preinstalled but works differently.
Unlike most reading apps, Play Books won't open a local EPUB directly. Instead, upload the file to your Google Play Books library at play.google.com/books (or via the Upload option inside the Android app), then read it from your library.
Everyone’s setup is a little different. If you’re unsure how to start reading or are running into trouble, a chat with an AI assistant can help if you describe your situation to it, e.g. Claude, ChatGPT, or Gemini.
