Optimize PNG

sudo apt install 

To optimize a PNG file, run

$ optipng -o7 file.png

-o selects the optimization level. The higher the level, the more compression trials. OptiPNG optimizes the given file in-place.

To make the file further smaller, we can remove the metadata from the PNG file by specifying –strip all:

$ optipng --strip all -o7 file.png
