good at reducing the pallet, a first step for images that have a limited number of colors, bad at actually compressing things though, for all formats tested.
## PNGs:
good ratios, though not as good as other options, though better compatibility
### pngcrush
Good, but should be ran before optipng, but isn't as good as it, use in tandom
### optipng
The best tool to really shrink pngs to be as small as they can be.
## WEBP
it's better than png, though I have a feeling more could be done to compress these
### ffmpeg
so far this seems to be the best way to compress webp images with a command that kinda looks like this one
```
```bash
ffmpeg -i input.webp -c:v libwebp -lossless 1 -q:v 100 -compression_level 6 output.webp
```
it's better than png, though I have a feeling more could be done
## AVIF
As far as I can tell, this format just sucks at its job, at least for lossless images
## JPEGXL
Really good at compression size, though it's not supported anywhere outside of safari as of now.
### cjxl
this command should do the trick for compressing
```bash
cjxl input.png output.jxl -q 100 -e 10
```
