This conversion maps KWD's structure, text encoding, images, and metadata into AZW3 while preserving layout, styling, and reflowability where possible.

Keep individual KWD files under 50–100 MB for fastest, most reliable conversions; large illustrated books may need compression.
To preserve layout and styling, choose 'original image quality' and ensure fonts used in the KWD are embedded or standard; avoid proprietary fonts.
For multiple books, use batch conversion with zipped KWDs and set a consistent quality profile to save time and ensure uniform results.
Note format limitation: AZW3 supports advanced CSS and embedded fonts but may not reproduce highly complex interactive KWD features or custom scripting.
