AZW3 at a glance
AZW3
Convert to AZW3 when producing an ebook for Kindle devices or Amazon-oriented reading environments, especially when the content benefits from more modern ebook styling than older AZW offers.
It is a good target for polished Kindle-ready releases and managed personal ebook libraries.
For neutral authoring and exchange, EPUB remains the more portable source format.
CDR at a glance
CDR
Convert to CDR when the recipient will continue editing or producing the artwork in CorelDRAW-based environments, especially in print, signage, or fabrication-adjacent workflows.
It is useful when native Corel compatibility is the priority.
For more neutral exchange, PDF, SVG, or EPS are usually easier handoff formats.
