How JPEG to PNG conversion works

JPEG decode → normalized image frames → PNG encode

Reading JPEG

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

Creating PNG

PNG output preserves lossless pixels and alpha, but this static target does not retain animation.
