A simple script to convert the grabage you collect through the internet (aka memes) and other unimportant images you have to lossy webp image which will save you some space. Past it into a directory and it will compress anything in it. It's very destructive use it wisely.
#!/usr/bin/bash
BSIZE=$(du -Ss $PWD | awk '{print $1}')
function finish(){
ASIZE=$(du -Ss $PWD | awk '{print $1}')
FSIZE=$((BSIZE-ASIZE))
echo $(python -c "print($FSIZE/1000.0)")MB
}
trap finish EXIT
find $PWD -maxdepth 1 -size -1024k -iname "*.jpg" -or -iname "*.png" | xargs -I '{}' sh -c '(echo converting "{}" && cwebp "{}" -mt -q 80 -o "{}".webp 2> /dev/null || true) && rm "{}"'
#Remove -maxdepth 1 to make it recursive (NOT RECOMMENDED)
