- painchoc 5y agoExactly. Dithering creates a lot of noise and PNG is poor choice to compress that.
- shadowfaxRodeo 5y agoit's the opposite way round. png is especially good at compressing dithered images. It's a reduced color palette, (in this case just black and white) so there's lots of repeated sequences. Which works very well with lossless compression.
