How do I open an AZW file online?

Upload your .azw file to ReadLoudly's free AZW reader. It opens Kindle AZW files in your browser without needing a Kindle device or the Kindle app.

AZW is Amazon's proprietary ebook format for Kindle devices. It is similar to MOBI but with additional DRM protection. ReadLoudly supports DRM-free AZW files for browser-based reading and listening.

Can I listen to AZW Kindle books with AI voices?

Yes. ReadLoudly reads AZW files aloud using natural AI text-to-speech with 1200+ voices across 40+ languages. Adjust speed, choose voices, and listen hands-free.

What is the difference between AZW, AZW3 and KFX?

AZW is the original Kindle format, AZW3 (KF8) added richer formatting, and KFX is Amazon's newest container. This reader handles DRM-free AZW and AZW3 files. KFX files need converting to AZW3 or EPUB first.

Is the AZW reader free to use?

Yes. Reading and listening to AZW files is free, with no account required to start and no watermark on anything. Paid plans — Core at $5/month, Plus at $10/month, Pro at $19/month — raise the upload size limit, unlock all 1200+ AI voices, add MP3 downloads and offline listening, and remove ads.

Does ReadLoudly support AZW as well as other formats?

Yes — AZW is fully supported on this page, and it is one of 24 formats ReadLoudly reads aloud: documents (PDF, DOCX, ODT, RTF), ebooks (EPUB, MOBI, AZW, FB2, CHM, LRF, LIT, PDB, RB), text and web files (TXT, HTML), comics (CBR, CBZ), and images (via OCR) (JPG, PNG, GIF, BMP, WEBP, TIFF, SVG). Upload an AZW file here and it opens straight away; any other format on that list has its own reader page.

Can I open AZW files on my phone or tablet?

Yes. This reader runs in the mobile browser on iOS and Android — nothing to install — so you can open an AZW file straight from your phone's Files app, an email attachment or a cloud drive. Playback continues in the background, and your position syncs to any other device you sign in on.

What happens to my AZW file after I upload it?

It is parsed to extract its text, then removed from the processing servers. ReadLoudly does not train models on your files, does not share them with third parties, and does not make them visible to anyone else. Signed-in users can choose to keep an AZW file in their own private library; a guest upload is discarded when the session ends.

What exactly is an AZW file?

AZW is Amazon's Kindle ebook format, the successor to MOBI. ReadLoudly opens it directly in the browser, so you do not need the original software that created it.

What if my file is not an AZW?

Every format gets its own reader page rather than being funnelled into one generic uploader, so nothing loses its format-specific handling. Nearest neighbours to AZW among ReadLoudly's ebooks: FB2, CHM, LRF, LIT. The Tools page lists all of them.
