The original was a 300dpi image, converted to Jpg.
Since it is sweeping colour, it does not matter in Format, since I encoded both of them with 100% clarity.
PNG uses a 48bit palette.
JPEG uses a variable palette.
PNG is a lossless format, great for all colours, but comes with Size to Quality curse.
JPEG is a lossy format, really good for smooth colours, not for high contrast images.
JPEG (at 100%) is a near 10:1 compression.
