How JPEG to APNG conversion works

JPEG decode → normalized image frames → APNG encode

Reading JPEG

JPEG input is decoded with its embedded orientation and compatible ICC color profile before conversion.

Creating APNG

APNG output preserves full-color animation and alpha, but file sizes can be larger than modern animated formats.
