About EPUB to AZW Conversion
What is the EPUB format?
EPUB stands for Electronic Publication — the open ebook standard maintained by the W3C. It is used by readers of Kobo, Apple Books, Google Play Books and most non-Kindle devices. Its strengths are text that reflows to any screen size, adjustable fonts, chapters and metadata; its drawback is that Kindle devices and many office tools cannot open it directly.
What is the AZW format?
AZW stands for Amazon Kindle eBook — Amazon's first proprietary Kindle wrapper around MOBI. It is used by Kindle owners with books bought before the AZW3 era. Its strengths are native Kindle support with bookmarks, notes and progress sync; its drawback is that locked to Kindle hardware and apps, and frequently DRM-protected.
What changes when you convert EPUB to AZW
EPUB and AZW are both reflowable ebook formats, so the conversion keeps chapters, the table of contents, cover art, metadata and inline images; what changes is which devices can open the file. Styling that AZW does not support is simplified rather than dropped, and DRM-protected EPUB files cannot be converted at all.
Leaving EPUB behind means leaving behind its main drawback: Kindle devices and many office tools cannot open it directly. What you get in return is what AZW does best — native Kindle support with bookmarks, notes and progress sync — which is why Kindle owners with books bought before the AZW3 era rely on it. Tip: send the finished AZW to your Kindle by email or USB; if the book has a cover, it is embedded so it shows in your library.
The conversion itself runs with Calibre and ImageMagick on encrypted servers. Files are deleted automatically once the AZW has been generated — nothing is stored or read — and no account is needed.
Why convert EPUB to AZW?
- Read the book on a device or app that does not support EPUB
- Keep bookmarks, progress and highlights in your usual ebook reader
- Fix a library where the same book exists in several formats
- Listen to it: open the AZW in the ReadLoudly reader and have it read aloud
EPUB to AZW — Frequently Asked Questions
Everything worth knowing before you convert a EPUB file to AZW.
Upload your EPUB above, adjust any EPUB-to-AZW options you need, and press Convert. The finished AZW is ready to download as soon as processing completes — no software to install and no account required.
Yes. EPUB to AZW conversion is free with no signup, and there is no watermark on the output. Signing in raises the file size limit and puts your jobs into the priority processing queue.
Guests can convert an EPUB of up to 50 MB into AZW. Signed-in users get higher ceilings — 200 MB on Core, 350 MB on Plus and 500 MB on Pro — which matters most when the source EPUB is image-heavy or book-length.
Your EPUB upload is encrypted in transit, converted, and then deleted automatically along with the AZW output. ReadLoudly does not read, retain long-term, train on, or share the contents of a EPUB file you convert here.
Most EPUB files finish in under 30 seconds. A large, image-heavy or multi-hundred-page EPUB can take a minute or two before the AZW is ready — the page updates on its own, so there is no need to refresh or resubmit.
Yes. Open the converted AZW in ReadLoudly's AZW reader and it can be narrated with 1200+ AI voices across 40+ languages. Going EPUB to AZW first is often the whole point — it puts the content into a format the reader handles natively.
No. ReadLoudly runs the EPUB to AZW conversion on its own servers with the same industry-standard tooling (Calibre and ImageMagick) you would otherwise install yourself, so it behaves identically on Windows, macOS, Linux, iOS and Android straight from the browser.
