AZW3 to G3 conversion is the process of transforming an eBook file in Amazon's AZW3 (Kindle Format 8) into a G3 format, typically used for legacy or specialized e-readers that require the G3 container. This conversion remaps formatting, metadata, and embedded resources so the book displays correctly on devices or applications that support G3.

AZW3 is a proprietary Amazon ebook format primarily used for Kindle devices, featuring advanced formatting and DRM support. In contrast, G3 is a simpler format that offers better compatibility with a broader range of ebook readers. While AZW3 focuses on enhanced display features, G3 prioritizes accessibility and smaller file sizes.
Keep individual AZW3 files under 50–100 MB for fastest, most reliable conversion; images-heavy books may require higher limits.
To preserve layout and typography, disable aggressive image recompression and choose the high-quality G3 output setting when available.
For large libraries, use batch conversion tools but convert a single representative file first to verify settings before processing many books.
Note format limitation: AZW3 supports advanced HTML/CSS and fonts that may not fully map to G3; expect potential reflow or font substitution for complex layouts.
