It is not much, but it is not nothing.

Thanks for this @C0rn3j.
Before I merge, please could you remove any changes from the tests/ directory?
Also, please could you share the commands/options/configurations/script used for the conversions made? Would be good to have that as a reference for how this optimization was done, and should be useful to have on-hand for future changes.

Sure thing, will do so when I find a bit of time

Took out the test dir

Found out GIFs can also be losslessly optimized, so another 2KB down on the loading animation, plus 0.6KB on the existing PNG optims due to additional --zopfli flag.
