APNG
APNG started as a Mozilla-driven attempt to bring better animation into the PNG ecosystem. Its practical relevance increased once modern browsers and toolchains treated it as a viable web animation target.

FAQ
Why convert JPEG 2000 to 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.
What changes when converting JPEG 2000 to APNG?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to APNG removes animation support. Moving to APNG adds streaming delivery.
What should I review after converting JPEG 2000 to APNG?
Validate output quality on representative files and confirm the target format behaves correctly in the destination workflow.
