This is for in the future when I want to compress more images or anyone else for that matter.

# Lossless
|
|
|
|
### https://squoosh.app/
|
|
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
|
|
```
|
|
|
|
## 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
|
|
```
|
|
|
|
# Vector
|
|
|
|
## SVGs:

great tool, if anyone knows how to squish them further, let me know, some manual work may go a long way to help shrink svgs, though I'm not doing that right now lol.

I may look into other formats soon as well, though these are the main two I'm currently using
