PEF Image files are raw image files mainly used for high-quality photography, whereas AZW3 is an ebook format designed for digital reading devices like Kindle. While PEF retains detailed image data, AZW3 focuses on text and layout compatibility to improve reading experience. Converting from PEF to AZW3 transforms raw images into a format optimized for ebooks and digital readers.
Keep individual PEF files under 50–100MB for faster, more reliable uploads; large raw files increase processing time and memory use.
Preserve quality by exporting PEF to high-quality JPEG or PNG as an intermediate step before AZW3 packaging; avoid excessive downsampling if you need detail.
For multiple files, batch-convert PEF to optimized JPEGs first, then compile those into a single AZW3 to speed up conversion and reduce errors.
Format-specific limitation: AZW3 is an eBook container and does not retain raw sensor data or adjustable raw parameters—final images must be rasterized (JPEG/PNG) before embedding.
