APNG at a glance
APNG
Convert to APNG when you need short, looping animation with transparency and image-like rendering quality.
It is a good target for interface demos, animated icons, stickers, overlays, product walkthrough fragments, and web assets that must preserve sharp text or crisp edges.
Choose APNG over GIF for better color and transparency, and over MP4 when a transparent animated image is easier to embed than a video element.
It is less appropriate for long clips, large dimensions, or bandwidth-sensitive video delivery.
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.
