About Converting AZW3 to EPUB
AZW3 is Amazon’s Kindle format that succeeded MOBI, adding better typography and styling. It targets modern Kindle devices and apps. When you need to move away from AZW3, the usual reason is simple: amazon-specific.
Converting your AZW3 e-book to EPUB solves that. EPUB is the open, reflowable e-book standard used by most readers except Kindle. Text adapts to any screen size, and the format supports images, styling and navigation. In practice you gain reflowable text for any screen and open standard. PrivConvert runs the whole AZW3-to-EPUB conversion in server memory and deletes your file the instant the EPUB is ready — nothing is stored, logged or reused.
When this conversion helps
- You need reflowable text for any screen
- You need open standard
- You need supported by most e-readers and apps
- Escaping a proprietary AZW3 file for the open EPUB standard
- Sharing a AZW3 e-book with someone whose software expects EPUB
Tips for best results
- Files up to 250 MB are supported, and you can batch-convert several AZW3 files at once; each is processed privately and deleted immediately.

Drag and drop your file into the upload area, click to browse your device, or paste a URL to a file hosted online. You can upload files up to 250 MB and batch convert up to 20 files at once.
Once uploaded, the conversion from AZW3 to EPUB starts automatically. The process runs entirely in an isolated environment - your data never leaves the secure pipeline.
Your converted file is ready instantly. Click the download button to save it to your device. The file is deleted from memory immediately after download.
A more private way to convert AZW3 files
Plenty of sites convert AZW3 files. Very few promise never to keep them — PrivConvert does, and backs it up with how the service is built.
Runs in any modern browser on Windows, macOS, Linux, Android and iOS — no install, plugin or desktop software needed.
Each job runs in an isolated in-memory sandbox, so most conversions finish in seconds instead of waiting in a queue.
We never keep a copy. Once your EPUB is delivered, both the original and the result are gone — there is nothing left to leak or misuse.
Every conversion runs in its own locked-down process with no network access, so files can never leak or interfere with one another.
