The real package cover—not a filename guess.
The extractor checks EPUB 3 cover-image properties, EPUB 2 cover metadata, and legacy guide references. It follows the same package references ebook readers use.
The downloaded image keeps its original bytes, format, and quality. Nothing is resized or recompressed, and the EPUB itself is not changed.
