I'm wondering if the dithered webp has any gains on the dithered png. Avif comes to mind but definitely still not enough browser support to really worry about it.
Okay! So I thought I'd already done my research and knew the answer to this. But I didn't know lossless webp was a thing! So I tried it again with a 640 x 800 picture of a parrot and this is what I got:
Original Image jpeg: 106KB
Orginal Image lossy webp: 44KB
Which means you can actually get better results with a dithered webp than png. So thank you for your comment. I'm going to get to work adding webp download to the tool.
Edit: anyone reading this who is wondering why Jpeg and lossy Webp get bigger after dithering them. Computerphile did a good video about it it's about how jpeg compression works.
