Amazon Ebook Format
AZW4 is the latest proprietary ebook format developed by Amazon for its Kindle devices. Introduced in 2018, AZW4 incorporates enhanced typography capabilities based on Amazon's Ember font rendering engine. This allows improved text formatting like drop caps, ligatures, positional fonts, and a left-aligned vertical viewing mode. AZW4 supports fixed layouts popular with graphic novels and illustrated books. It builds on the previous KF8 format (AZW3) with features optimized for the latest Kindle readers. As with other AZW formats, Amazon's DRM controls usage rights and restricts AZW4 books to Kindles. The .azw4 file extension is used. While more advanced, AZW4 continues Amazon's philosophy of a closed ecosystem binding readers to Kindle devices and apps via proprietary formats. But AZW4 offers a premium reading experience for dedicated Kindle users.
