Plain text strips formatting entirely — no fonts, no layout, no images. Convert to TXT when you need to pipe content into a script or CSV import, or when a legal / archival requirement specifies "no formatting". Also the right choice for extracting the substantive content from a PDF for OCR post-processing or text-analysis workflows.
Technical comparison of the two formats — useful for deciding which to use, or for confirming what changes during conversion.

AZW3, also known as Kindle Format 8 (KF8), is Amazon's modern ebook format introduced in 2011 as the successor to MOBI. Built on HTML5 and CSS3, AZW3 supports advanced typographic features including embedded fonts, drop caps, SVG graphics, fixed-layout pages, and responsive design that adapts to different Kindle screen sizes. It provides a significantly richer reading experience compared to the older MOBI format.
AZW3 is Amazon's proprietary format and only works on Kindle devices and Kindle reading apps. It takes full advantage of Kindle's enhanced typesetting engine, supporting features like X-Ray, Word Wise, and improved font rendering. AZW3 files use more efficient compression than MOBI, resulting in smaller file sizes. While AZW3 is the preferred format for sideloading content to modern Kindles, it cannot be read on other eReaders like Kobo, Nook, or Apple Books without first converting to EPUB.
