If your dataset allows it, I would look at pngquant for "lossy" compression of PNG images by means of color quantization: https://pngquant.org/ https://pngquant

This works absolute wonders if you are talking about images with a limited amount of colors and without many gradients. I use it to compress screenshots of websites, which, if you think about it, are mostly large blobs of uniform colors with hard edges. I also use it every time I want to include a screenshot from my desktop in some publication or email. The savings in filesize are too good to be true without any apparent loss of visual fidelity.
