How to Convert and Send EPUB Files to Kindle Using Send to Kindle and Calibre
The quickest way to get free, public domain EPUBs onto your Kindle is to use Amazon’s Send to Kindle service — and despite the old advice, you do not need a separate converter or software. In fact, many modern Kindle models accept EPUB files directly, so the process is simpler than ever.
<div class="tldr-box"> <div class="tldr-title"><span>TL;DR — Quick Summary</span></div>You can send EPUB files to your Kindle without any third‑party conversion software. Use Amazon’s Send to Kindle website, the mobile app, or email your EPUB to your Kindle address. For older Kindles that only support MOBI, use the free Amazon‑provided Send to Kindle desktop app (which handles conversion automatically). No need for Calibre, KindleGen, or any other ebook tool.
</div>Why You Can Now Send EPUB Directly to Kindle
For years, Kindle devices only supported the proprietary MOBI format. Readers had to convert EPUB to MOBI using conversion tools before sending. That changed in 2022. Amazon now accepts EPUB files through the official Send to Kindle service and converts them on their end — you never touch a converter. This is great news if you love classic public domain books downloaded from sources like ZipMyBook's curated collections, which deliver all titles in EPUB and PDF.
What Kindle Models Support Direct EPUB Sending?
- Kindle Paperwhite (10th generation and later)
- Kindle Oasis (all generations)
- Kindle (11th generation and later)
- Kindle Scribe
- Fire tablets with the Kindle app
Older Kindle models (e.g. 8th generation and earlier) still require MOBI. The Send to Kindle service handles that conversion automatically when you send an EPUB — you do not need to convert beforehand.
Three Ways to Send EPUB Files to Kindle Without Any Software
Amazon provides three official methods, all free and no extra tools.
Method 1: Use the Send to Kindle Website
- Open www.amazon.com/sendtokindle in any browser (desktop or mobile).
- Drag and drop your EPUB file onto the page, or click “Browse from computer.”
- Select the target Kindle device or app and click “Send.” The file will arrive within minutes.
EPUBs sent this way are converted to Kindle format in the cloud. No software installed on your computer.
Method 2: Email the EPUB to Your Kindle Address
- Find your unique Kindle email address in the “Manage Your Content and Devices” page on Amazon, under the “Devices” tab.
- Add the sender email to your “Approved Personal Document E-mail List” (same page).
- Compose an email with the EPUB file attached and send it to your Kindle address. Amazon converts it and delivers it wirelessly.
This works for any Kindle, including older models. You can also send PDFs this way.
Method 3: Use the Official Send to Kindle App (Desktop or Mobile)
- Download the free Send to Kindle app for Windows or Mac from Amazon’s website.
- Install and open the app, then drag EPUB files onto the window.
- Choose your Kindle device and click “Send.” The app handles any conversion needed.
Alternatively, the Amazon Kindle app for iOS and Android includes a built‑in “Send to Kindle” option when you share a file from another app. This is seamless for EPUBs already on your phone.
What About Older EPUBs That Don’t Convert Well?
Most public domain EPUBs — especially those from reputable curated stores — are well‑formatted and convert cleanly. If a file has unusual fonts or layout, try these quick fixes:
- Re‑download the EPUB from the source. Many sites offer multiple versions.
- Send the file as a PDF instead. Kindle handles PDFs natively (no conversion).
- Limit file size to under 50 MB for email delivery, or 200 MB via the website.
How to Get Public Domain EPUBs Worth Reading
The real challenge isn’t the sending process — it’s finding great books that are free to own. Thousands of classics published before 1928 are legally in the public domain. For example:
- Pride and Prejudice by Jane Austen (1813)
- Meditations by Marcus Aurelius (circa 180 AD, translated later)
- Dracula by Bram Stoker (1897)
- Frankenstein by Mary Shelley (1818)
- The Time Machine by H.G. Wells (1895)
- The Adventures of Sherlock Holmes by Arthur Conan Doyle (1892)
- The Yellow Wallpaper by Charlotte Perkins Gilman (1892)

Why You Don’t Need Calibre or Any Converter
Many older guides tell you to use Calibre to convert EPUB to MOBI. That advice is outdated. Amazon’s Send to Kindle already performs the conversion automatically on its servers or in the desktop app. You never have to learn a new program or worry about formatting errors.
The only reason to use a separate converter today is if you want to edit metadata or strip DRM (irrelevant for public domain books). For free classics, just send the EPUB as‑is. It works.
Frequently Asked Questions
Can I send EPUBs from my phone?
Yes. Use the Kindle app’s share‑to‑Kindle feature or the Send to Kindle mobile website.
Do Kindle devices show EPUB covers?
Usually yes. Amazon’s conversion preserves the cover image in most cases.
Is there a file size limit?
Email: 50 MB. Website and app: 200 MB. Public domain EPUBs are rarely over 10 MB, so no issue.
What if I already have Calibre?
You can still use it, but this article does not cover or recommend Calibre. The official Send to Kindle methods are simpler and avoid potential formatting bugs.
Share the Classics Without the Hassle
Once you know how to send EPUB files to Kindle using Send to Kindle, you can fill your library with timeless literature in minutes. Every book in the public domain is yours to keep and share — no subscriptions, no DRM, no cost. ZipMyBook's curated collections package the best of those titles into themed sets (Gothic Horror, Stoic Philosophy, Victorian Literature, and more) so you can start reading right away.
