Btw, I recommend using
https://squoosh.app/ to easily recompress images to post here, 4chan gives you 4mb per image, so make sure to use most of it for better looking images. (quality 100 MozJPEG gives me only 3mb for this one, otherwise I'd make it closer to 4mb)
Sometimes you don't even need to convert them to .jpg, using OxiPNG at effort 3 gives an average of 30% in filesize reduction while maintaining the exact same quality.
