Command Crate Optimize PNG images recursively (optipng)
find . -name "*.[Pp][Nn][Gg]" -printf ' optipng > %p\n' -exec optipng -preserve -clobber -nc -nb -o7 -zm1-9 -quiet {} \;This command recursively locates all PNG files (*.png or *.PNG) and uses optipng to apply maximum optimization (-o7), varying compression levels (-zm1-9), and other options like preserving metadata (-preserve) and avoiding overwriting existing files (-nc). The -quiet option suppresses unnecessary output during optimization.
