Does EPUB Work on Kindle? Complete Guide for 2027

Are you wondering if Kindle now natively supports EPUB files? With Amazon's recent policy shift, the landscape of digital reading has changed dramatically—learn everything you need to know.

Does Kindle Support EPUB Files Natively in 2027?

In the past, Kindle devices did not support EPUB format directly. Amazon relied on proprietary formats like MOBI, AZW, and KFX, making conversion necessary for most users.

However, as of January 20, 2026, Amazon has officially changed its stance. Verified purchasers can now download DRM-free EPUB and PDF files directly from Amazon's platform, marking a significant shift in format support.

This new support for EPUB is limited to DRM-free files. If you're trying to read DRM-protected EPUBs, you'll still need to use conversion tools or remove DRM legally. Native support for EPUB on Kindle is now mostly about DRM-free files, which can be easily transferred via email transfer or through the Send to Kindle app.

Current EPUB Support Status

Before January 2026, Kindle devices operated in a closed ecosystem with formats like MOBI, AZW, and KFX. Post-policy change, verified users can directly download EPUB and PDF files without conversion if the files are DRM-free.

This means that for any EPUB files published after December 2025, you can now enjoy straightforward support without fussing over conversion. For older DRM-free titles, publishers or authors may need to manually enable EPUB download options via the Kindle Direct Publishing dashboard.

Differences Between EPUB and Kindle Formats

EPUB is an industry-standard format supported by most e-readers, including Kobo, Nook, and PocketBook devices. Kindle's proprietary formats, like MOBI and AZW, are optimized for Amazon devices and apps.

Understanding these differences helps you decide when to use format support or conversion. DRM-free EPUBs can now be used across multiple devices without conversion, making your digital library more flexible. However, if you're reading on a Kindle Paperwhite or Oasis, converting EPUB to MOBI or AZW remains a common step for full compatibility.

How to Send EPUB Files to Kindle

Getting EPUB files onto your Kindle is now simpler thanks to various methods. The Send to Kindle app is one of the most user-friendly options. It allows drag-and-drop or email-based transfer of EPUB and other files.

Supported on Windows, Mac, and mobile devices, the Send to Kindle app streamlines the process. Files under 200 MB are automatically converted to Kindle formats like AZW3 or KFX, ensuring seamless reading.

Using Send to Kindle App

With the Send to Kindle app, you can easily transfer EPUB files by dragging them into the app or sending them via email. It supports various file formats, including PDFs and EPUBs, and simplifies the process of format support.

Once sent, files under 200 MB are converted automatically, making it easier to read on your Kindle device or Kindle app. For larger files, consider compressing or splitting your documents beforehand.

Sending EPUB via Email

Each Kindle device has a unique email address found in 'Manage Your Content and Devices' on Amazon. Attach your EPUB files to an email and ensure your email address is whitelisted in the settings. For more on this, see our guide on does kindle take.

EPUB files sent via email are converted automatically if under 200 MB, and they appear in your library within minutes. This method is especially useful for quick transfers or batch uploads of DRM-free EPUBs.

Best Practices for Sending EPUB Files

To avoid issues, compress large EPUB files or split lengthy documents into smaller parts under 200 MB. Always ensure EPUB files are DRM-free to prevent format compatibility problems.

Keeping your Kindle firmware updated is crucial for optimal file transfer and format support. Regular updates improve support for newer formats and fix bugs that could hinder EPUB reading.

Converting EPUB for Kindle: Tools and Techniques

While direct support for DRM-free EPUBs has improved, many users still prefer converting EPUB to Kindle-specific formats like AZW3 or KFX for better formatting and features.

Calibre remains the gold standard for EPUB conversion. It’s a free, open-source tool that lets you customize formatting, fonts, and layout before transferring files to your Kindle. Using Calibre gives you control over format support and ensures your EPUBs look great on your device.

Using Calibre for EPUB Conversion

Calibre can convert EPUB to formats like AZW3, MOBI, or KFX, making it highly versatile. It allows detailed customization of your eBook, including font sizes, margins, and cover images.

To use Calibre, simply add your EPUB file, choose the output format, and click convert. Afterward, transfer the converted file via email transfer or through the Send to Kindle app for optimal format support on your device.

Other Conversion Tools and Software

Automateed offers AI-powered tools that simplify creating and formatting EPUBs, especially for authors. Online converters and paid software are also available for quick format conversion from EPUB to MOBI or AZW3.

Always verify the DRM status before conversion. DRM-protected EPUBs require removal of DRM via legal means or publisher permissions to ensure compatibility with Kindle devices.

Best Practices for EPUB Conversion

After conversion, check formatting and readability on your Kindle or Kindle app. Small layout issues can be fixed by editing the EPUB or adjusting settings in Calibre.

Test converted files on different devices to confirm consistency. Removing DRM, when permitted, can vastly improve your conversion experience and file compatibility.

Amazon's EPUB Support Updates and Policy Changes

Amazon's January 2026 update marks a turning point in eBook management. Verified purchasers can now directly download DRM-free EPUB and PDF files, ending years of ecosystem restrictions. For more on this, see our guide on converting kindle epub.

This policy change allows authors and publishers to publish in EPUB or PDF formats alongside proprietary formats, broadening the options for distribution and reader access.

The January 2026 Policy Shift

This shift ended over 15 years of ecosystem restrictions, enabling more open format support for Kindle users. Now, EPUB files can be downloaded directly if they are DRM-free, simplifying file transfer methods.

Amazon has also integrated new eBook management tools within KDP, giving publishers more control over format and DRM settings, aligning with industry trends toward openness.

Implications for Authors and Publishers

Authors can now reach broader audiences by offering EPUB versions alongside traditional Kindle formats. The increased control over distribution helps in managing DRM protection and format support.

With new tools in the KDP portal, publishers can easily opt for DRM-free EPUBs or set specific DRM protections, balancing accessibility with rights management.

Future Outlook for EPUB on Kindle

Expect continued support and improvements for EPUB compatibility, including potential enhancements in format conversion and DRM options. Staying updated with Amazon updates ensures maximum benefit for both authors and readers.

Overall, this change signals a move toward greater openness in digital publishing, with EPUB becoming an integral part of Kindle’s ecosystem.

Troubleshooting Common EPUB Issues on Kindle

Like any digital format, EPUB can present challenges, especially with large files or DRM restrictions. Common issues include file size limitations, formatting errors, and delivery failures.

To address these, use tools like Calibre to optimize EPUB files before transfer. Compress large EPUBs or split documents into smaller parts to stay under 200 MB.

Verify DRM status—DRM-protected EPUBs will not be supported unless DRM is removed legally. Keep your Kindle firmware and apps updated to support the latest formats and fix bugs.

File Size and Format Compatibility

Large EPUB files often require compression or splitting into smaller chunks. Files over 200 MB may fail during email transfer or conversion.

Ensure EPUBs are DRM-free for seamless support for EPUB files. Firmware updates improve file compatibility, especially on Kindle Paperwhite or Oasis.

Conversion and Formatting Problems

If formatting looks off after conversion, use Calibre to tweak layout and readability. Always check for layout issues and test on multiple devices. For more on this, see our guide on long does take.

Removing DRM, when legally permissible, improves conversion quality and file compatibility, especially for complex EPUBs with images or embedded fonts.

Delivery Failures and Settings

Whitelisting your email address in Amazon's Content & Devices Settings can prevent delivery failures. Confirm your internet connection and email account status before sending.

If issues persist, contact Amazon support or revisit your file transfer methods for troubleshooting.

Alternative Ebook Formats for Kindle

While support for EPUB files has improved, Kindle natively supports formats like MOBI, AZW, KFX, and PDF. Converting EPUB to MOBI or AZW3 is often necessary for full support, especially on Kindle Paperwhite or Oasis.

Using multiple formats allows you to maximize compatibility across devices and platforms. Export EPUBs in industry-standard formats for sharing or archiving, and convert as needed for device-specific features.

Supported Formats and Their Uses
