What is a azw file?
AZW is Amazon’s proprietary eBook format, built specifically for Kindle devices and the Kindle app. It’s based on the older MOBI format but with better compression and Amazon’s own DRM baked in. If you’ve ever bought a Kindle book, it almost certainly landed on your device as an AZW file.
The format does what Kindle needs it to do well. Bookmarks, annotations, last-read positions, built-in dictionary lookups. It’s optimized for reading, not for sharing. That’s the tradeoff.
That DRM is the catch. Most AZW files purchased through Amazon are locked to your specific account. You can’t just send one to a friend or open it in a different app. It lives in the Kindle ecosystem and largely stays there. Un-DRMed AZW files (think manuscripts, review copies, self-published drafts) are more flexible and can be managed with tools like Calibre or converted to EPUB or PDF for reading elsewhere.
There are also a couple of variants worth knowing. AZW3 is the newer version with better formatting support. AZW4 is used for PDF-style fixed-layout content. Most people just call all of them “Kindle files” without thinking twice about which version they’re dealing with.
If you’re an indie author, publisher, or beta reader sharing manuscripts outside the Kindle ecosystem, AZW files can be a headache for anyone without a Kindle or the app installed. That’s exactly the gap ShareOtter fills — recipients can read your AZW files directly in the browser, no app, no device, no friction.

How to Share azw eBooks Online
Three steps. No account, no software, no waiting around.
Select or Drop your File
Drag your AZW into the upload box above, or click to browse. Either way works.
Let it upload
Watch the progress bar. Most AZW files are done in a few seconds. Bigger files can take a little longer.
Copy your link
Done. Grab the link and send it anywhere. Slack, email, text, WhatsApp wherever your file needs to go.
Everything You Need to Share Files, Nothing You Don't
Sharing a file shouldn't mean losing control of it the moment you hit upload.
Instant Shareable Link
Upload once, get a link instantly. No waiting on emails to send, no attachment size limits bouncing your file back — just a clean URL you can paste anywhere, ready the second your upload finishes.
Password Protection
Lock any file behind a password before sharing. Only people with both the link and the password can open it, so sensitive files stay sensitive even if the link ends up somewhere you didn't intend.
Link Expiry Control
Set a link to expire after a day, a week, or whatever window makes sense. Once it's gone, it's gone — no stale links floating around in old emails months later.
Comments for Feedback
Let people comment directly on the file instead of replying in a separate email thread. Feedback stays attached to exactly what it's about, so nothing gets lost translating between a file and a conversation.
Email-Gated Access
Restrict a file to specific people by email. They'll get a magic link to sign in and view it — no password to share, no guessing who actually opened your file.
No Signup Required
Share a file in seconds without creating an account. Drop it, get your link, send it — sign up later only if you want to manage files long-term.
