How do I convert a DOC file to AZW3?

What is the benefit of converting DOC to AZW3?

AZW3 (KF8) is Kindle's native format, designed for e-ink screens with reflowable text. Unlike DOC, it supports justified text, embedded fonts, and vector images, and typically produces smaller file sizes for ebook distribution.

How does the conversion handle images and formatting from DOC?

During conversion, images are re-encoded to JPEG or PNG (depending on transparency) and resized to fit Kindle's screen constraints. Basic formatting like bold, italics, margins, and headings are preserved; complex tables and embedded objects may be simplified to maintain reflowability.
