How to Convert Kindle Books to EPUB: Easy Steps in 2025

I often run into Kindle books that won't open on other devices because the format isn't supported, and this is a common obstacle for anyone trying to read the same title across multiple apps or eReaders. Kindle files rarely work outside the Amazon ecosystem unless they're converted to EPUB, and this limits how you organize or back up your digital library. If you're preparing to convert Kindle books to EPUB for easier access on different devices, the steps below outline how to use several common converters and what to expect during the process.

Why You Want to Convert Kindle Books to EPUB

Amazon Kindle uses its own file formats and Digital Rights Management (DRM) to control how books are copied and shared. Titles purchased from the Kindle Store are usually saved as PRC, AZW, TPZ, MOBI, or KFX files, which are built to work with Kindle devices or the Kindle app. Because of this design, Kindle books in these formats can't normally be opened directly on other popular e-readers such as Sony Reader, Nook, or Kobo, or in many reading apps on an iPad.

This format lock-in is the main reason people look for ways to convert Kindle books to EPUB. EPUB is a widely used open eBook format that works with most e-readers and computer operating systems, so one EPUB file can follow you across different devices. Kindle services like Whispernet are convenient if you stay inside Amazon's system, but readers who switch between several devices often find EPUB more practical. With a Kindle to EPUB converter, you can bypass the format barrier and keep reading Kindle books on the devices you use every day.

FAQs

What should I do if my converted EPUB file won't open?

If you are having trouble opening an EPUB file, try the following steps:

1. Verify the file extension: Check that the file is actually saved with the .epub extension and not under a different format by mistake.
2. Try other readers: Try opening the file in another EPUB reader. Common options include Apple Books, Calibre, FBReader, and Adobe Digital Editions.
3. Validate EPUB file: Use an EPUB validator such as EPUBCheck to test the file and see whether there are structural errors that prevent it from opening.
4. Try another format: Convert the EPUB file to a different format (such as MOBI or PDF) with a tool like BookFab Kindle Converter, and check whether the converted file opens correctly.

Do I need to remove DRM from Kindle books before converting them to EPUB?

To convert many Kindle books to EPUB, the DRM usually has to be removed first. DRM on a Kindle title is designed to control copying, sharing, and format changes, which includes converting the file into other formats. Once the DRM is removed within the scope allowed by local law, the book can be processed by conversion tools and saved as an EPUB file.

Is it legal to convert Kindle books to EPUB?

The answer depends on your jurisdiction and on how the book is used:

• In countries that have laws similar to the DMCA in the United States, removing DRM copy protection itself can be illegal, even if the conversion is only for personal use.
• If the original Kindle file (such as MOBI or AZW) is clearly in the public domain, for example a title from Project Gutenberg, you can usually convert and use it freely.
• If the book is copyrighted but not protected by DRM, many regions allow format shifting for personal use, meaning you may convert it to EPUB as long as the copy stays for your own reading.

If you are unsure about local rules, check the copyright laws in your country or seek legal advice before removing DRM.

Conclusion

Converting Kindle to EPUB format is now simpler than ever, thanks to the variety of reliable tools available in 2025. Whether you choose the simplicity of BookFab Kindle Converter, the versatility of Calibre with a DeDRM plugin, the batch processing capabilities of imElfin Ultimate, or the ease of Convertio's online platform, there's an option to meet every reader's demands.
