The three ways to get ebooks onto your Kindle
You can move ebooks to your Kindle in three ways: buy them directly from Amazon, send them from your computer using a USB cable, or email them to your Kindle's unique email address. The method you choose depends on where the ebook came from and whether you own the device outright or are borrowing it.
Most people use the first method — buying from Amazon — because it's the fastest and requires no cables or email setup. But if you already own an ebook file on your computer, or you borrowed an ebook from your library, the other two methods let you read it on your Kindle without buying it again.
Key Takeaways
- Amazon's Kindle Store is built into your device and lets you buy ebooks that read automatically, though you can also send ebooks from your computer using a USB cable.
- Your Kindle has a unique email address (found in Settings) that accepts ebook files sent as attachments, which then appear in your library within minutes.
- Library ebooks borrowed through apps like Libby or OverDrive can be sent to Kindle directly from the app, though some publishers restrict this feature.
- Ebook files must be in a format your Kindle reads — common formats like PDF, MOBI, and AZW work, but EPUB files need conversion first.
- Once an ebook reaches your Kindle, it stays in your library even if you delete it from the device, so you can re-read it later without paying again.
Buying ebooks directly from Amazon
Open the Kindle Store on your device by tapping the Store icon (usually at the top of the home screen), search for the title you want, and tap Buy. The ebook downloads to your device within seconds and appears in your library. You own this copy permanently — it stays in your Amazon account even if you delete it from the device, and you can re-read it to any Kindle you own.
If you have a Kindle Unlimited subscription, many ebooks in the Kindle Store are included at no extra cost. Tap the title, look for the "Read for Free" button, and tap it instead of Buy. The ebook downloads the same way.
Prices in the Kindle Store vary widely. Some ebooks cost less than print versions, some cost the same, and some cost more. If you see a price you don't want to pay, check whether your library has the same title through Libby or OverDrive — those services are free and let you borrow ebooks for two to three weeks.
Sending ebooks from your computer using a USB cable
Connect your Kindle to your computer with a USB cable. Your computer will show the Kindle as a removable drive or external storage device. Open that drive and look for a folder called Documents. Drag your ebook file into the Documents folder, then safely eject the Kindle from your computer.
The ebook appears in your library within a few seconds. Your Kindle reads PDF, MOBI, AZW, and several other formats, but not EPUB — the most common ebook format from libraries and independent publishers. If you have an EPUB file, you'll need to convert it first using a free tool like Calibre (a desktop program) or an online converter.
This method works for any ebook file you own, whether you bought it elsewhere, borrowed it from a library, or received it from a friend. The file stays on your device until you delete it, and it doesn't sync across multiple Kindles the way Amazon Store purchases do.
Emailing ebooks to your Kindle address
Every Kindle has a unique email address that accepts ebook files. Find it by opening Settings on your device, tapping Your Account, and looking for Send-to-Kindle Email. It will look something like yourname@kindle.com.
From your computer, open your email and compose a new message to that address. Attach your ebook file (PDF, MOBI, AZW, or other supported formats — not EPUB without conversion). Leave the subject line blank or write anything you want. Send the email.
Within a few minutes, the ebook appears in your Kindle library. This method works from any email account, so you can send ebooks to yourself from work, from a friend's computer, or from your phone. Like the USB method, the file stays only on your Kindle unless you also buy it from Amazon.
Borrowing library ebooks and sending them to Kindle
If you borrow an ebook through your library's app — usually Libby, OverDrive, or Hoopla — you can often send it directly to your Kindle. Open the ebook in the app, look for a menu or share button (usually three dots or lines), and select Send to Kindle. The app asks for your Send-to-Kindle email address, and the ebook appears in your library within minutes.
Not all publishers allow this. If you don't see a Send to Kindle option, the publisher has restricted it. In that case, you can still read the ebook on your Kindle by reading it in the library app itself — most library apps work on Kindle devices, though the reading experience is usually slower than reading a native ebook file.
Library ebooks expire automatically when your loan period ends (usually 14 or 21 days). When that happens, the ebook disappears from your Kindle library. You can borrow it again when ready if you want to re-read it.
Converting EPUB files so your Kindle can read them
EPUB is the standard format for library ebooks and independent publishers, but Kindle devices don't read EPUB natively. If you have an EPUB file, you need to convert it to MOBI or AZW format first.
The easiest free tool is Calibre, a desktop program you read and install on your computer. Open Calibre, click Add Books, select your EPUB file, then click Convert Books. Choose MOBI or AZW as the output format and click Convert. Calibre creates a new file in the format your Kindle reads. Then use the USB cable method or email method to move the converted file to your device.
If you don't want to install software, online converters like CloudConvert or Zamzar let you upload an EPUB file, choose MOBI as the output format, and read the converted file. The process takes a minute or two. Then email the converted file to your Kindle address or move it via USB cable.
Troubleshooting ebooks that won't appear on your Kindle
If you sent an ebook to your Kindle and it didn't appear, check that you used the correct Send-to-Kindle email address. Open Settings, tap Your Account, and verify the address. Also check your email's spam or junk folder — sometimes the confirmation email from Amazon ends up there, which can delay delivery.
If you used the USB cable method, make sure you safely ejected the Kindle from your computer before unplugging the cable. If you unplugged it while files were still transferring, the ebook may not have copied completely. Reconnect the device and try again.
If the ebook file is in EPUB format, your Kindle won't read it. Convert it to MOBI or AZW first using Calibre or an online converter, then send the converted file.
If you're trying to send a library ebook and the Send to Kindle option doesn't appear, the publisher has restricted that feature. You can still read the ebook in the library app on your Kindle, or borrow a different edition if one is available.
Frequently Asked Questions
Can I send an ebook to someone else's Kindle?
Yes, if you have their Send-to-Kindle email address. Email the ebook file to that address and it will appear in their library. However, some publishers restrict this — if the file is copy-protected, it may not send. Library ebooks almost never send to other devices because they're tied to the borrower's account.
What happens to ebooks I send via email if I delete them from my Kindle?
They disappear from your device, but you can send them again by emailing the file to your Kindle address a second time. Unlike Amazon Store purchases, emailed ebooks don't stay in a cloud library — they only exist on your device until you delete them.
Can I read EPUB files on my Kindle without converting them?
No, Kindle devices don't support EPUB format. You must convert EPUB to MOBI or AZW first using Calibre or an online converter. After conversion, you can send the file to your Kindle using email or a USB cable.
Do I need WiFi to read ebooks onto my Kindle?
For Amazon Store purchases and emailed ebooks, yes — your Kindle needs WiFi to read them. For the USB cable method, no — you can transfer files without any internet connection, as long as your computer is connected to the cable.
Can I send a PDF to my Kindle?
Yes, Kindle devices read PDF files. Email the PDF to your Send-to-Kindle address or move it to your device via USB cable. PDFs appear in your library the same way ebook files do, though the reading experience may be less smooth if the PDF wasn't formatted for small screens.
