Does the Kindle Paperwhite support EPUB?

Yes — the Kindle Paperwhite 11th generation (2021) received native EPUB support via a firmware update in 2022. Firmware 5.16.2.1.1 or later is required. Older Paperwhite models (10th gen and earlier) do not support EPUB natively and require converting to MOBI or AZW3 first.

How do I put an EPUB on my Kindle?

Three methods: (1) Send to Kindle web at send.amazon.com — upload the EPUB and select your device. (2) Send to Kindle app on Mac, Windows, Android, or iOS. (3) USB cable — connect Kindle as a USB drive and copy the EPUB to the Documents folder. Methods 1 and 2 require Wi-Fi; USB works offline.

What Kindle models support EPUB natively?

Kindle models from 2021 onwards support EPUB natively after firmware update: Paperwhite 11th gen, Paperwhite Signature Edition, Kindle 11th gen (2022), Kindle Scribe (2022), and Kindle Colorsoft (2024). Older models including Kindle Oasis 3rd gen (2019) and Paperwhite 10th gen (2018) do not support EPUB.

Does Kindle convert EPUB to another format?

Yes. When you transfer an EPUB to a compatible Kindle, the device converts it to Amazon's internal KFX format. This conversion happens transparently on-device. The reading experience is the same as any other Kindle book — the format conversion is invisible to the user.

How do I convert EPUB for older Kindle models that don't support EPUB?

Use Calibre: ebook-convert book.epub book.azw3 for newer older models, or ebook-convert book.epub book.mobi for the oldest devices. AZW3 is preferred over MOBI as it supports more formatting. You can also email the EPUB to your @kindle.com address — Amazon will convert it automatically if your account has an eligible device.

Kindle Paperwhite and EPUB: Native Support, What Changed, and How to Use It

June 12, 2026 · 6 min read

For most of Kindle's history, Amazon refused to support EPUB — the universal e-book format. That changed in 2022 when Amazon added native EPUB support to Kindle. Here's what this means, which models support it, and how to get EPUB files onto your Kindle today.

Which Kindle Models Support EPUB Natively?

Model	Release year	Native EPUB support
Kindle Paperwhite (11th gen)	2021	Yes (via firmware update, 2022)
Kindle Paperwhite Signature Edition	2021	Yes
Kindle (11th gen)	2022	Yes
Kindle Scribe	2022	Yes
Kindle Colorsoft	2024	Yes
Kindle Paperwhite (10th gen and earlier)	2018 and earlier	No — must convert to MOBI first
Kindle Oasis (3rd gen)	2019	No

To check your Kindle's firmware version: Settings → Device Options → Device Info. Firmware 5.16.2.1.1 or later adds EPUB support.

How to Transfer EPUB Files to a New Kindle

Method 1: Send to Kindle (Web) — Easiest

Go to send.amazon.com in any browser
Sign in with your Amazon account
Click "Send a document", upload your EPUB
Select your Kindle device
The EPUB appears in your library within a minute

Method 2: Send to Kindle App

Install the Send to Kindle app (Mac, Windows, Android, iOS). Right-click any EPUB file and choose "Send to Kindle". Or use the share menu on mobile.

Method 3: USB Cable

Connect your Kindle via USB
It appears as a USB drive
Copy EPUB files to the Documents folder
Safely eject and disconnect

USB transfer works without an internet connection and doesn't require an Amazon account.

What Happens to the EPUB on Kindle?

When you transfer an EPUB to a 2022+ Kindle, Amazon converts it to their internal KFX format on-device. This conversion is transparent — you see and read it as normal. The original EPUB remains accessible for re-conversion if needed.

EPUB 3 features supported on Kindle (2022+):

Reflowable text ✓
Custom embedded fonts ✓
Tables ✓
Images ✓
Basic CSS styling ✓
Fixed-layout EPUB — partial (varies by model)
Media overlays (audio sync) — not supported

Older Kindles: Convert EPUB to MOBI First

If you have a Kindle from 2019 or earlier, you need to convert EPUB to MOBI before transferring:

# Using Calibre command line
ebook-convert book.epub book.mobi

# Or AZW3 (better quality, Kindle-specific)
ebook-convert book.epub book.azw3

AZW3 is preferred over MOBI for newer content — it supports more CSS and larger file sizes. MOBI is the fallback for the oldest Kindle models.

Converting PDF to EPUB for Kindle

PDFs don't read well on Kindle — fixed layout, tiny text, no reflow. The best approach:

Convert PDF to EPUB3 with toolkit.bot — handles scanned PDFs, two-column layouts, tables
Transfer via Send to Kindle or USB

This produces a reflowable reading experience with proper font size control, unlike viewing the PDF directly in Kindle's built-in PDF viewer.
