What is it?
AZW3, also known as Kindle Format 8 (KF8), is a proprietary ebook format introduced by Amazon in late 2011 with the Kindle Fire. It succeeded the original AZW/MOBI-based format and brought richer formatting to Kindle ebooks.
AZW3 supports a subset of HTML5 and CSS3, enabling improved layout, styling, and embedded media. Like MOBI, it is built on the Palm Database container and is often packaged to stay backward-compatible with older MOBI readers, while remaining tied to Amazon's Kindle ecosystem and DRM.

Disadvantages
AZW3 is an Amazon proprietary format and is frequently DRM-protected, limiting use outside Kindle.
Outside Kindle devices and apps, AZW3 requires conversion to open in most other e-readers.
Amazon's newer KFX format adds advanced typesetting, so AZW3 is no longer the latest Kindle format.

Software for handling AZW3 files can be categorized into professional tools, free/open-source options, browser-based applications, and built-in readers. Professional tools are best suited for users needing advanced features, while free/open-source options cater to those seeking budget-friendly solutions. Browser-based applications offer convenience and accessibility, while built-in readers provide basic functionality for casual users.
When choosing software for AZW3, key decision factors include feature fidelity, the need for editing versus viewing, cost models, and platform compatibility.
