How PNG to APNG conversion works

PNG decode → normalized image frames → APNG encode

Reading PNG

PNG input preserves lossless pixels, transparency, and compatible color information.

Creating APNG

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