How BMP to APNG conversion works

BMP decode → normalized image frames → APNG encode

Reading BMP

BMP input is decoded as an uncompressed or simply compressed bitmap with limited metadata.

Creating APNG

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