+To optimize a PNG file, run
+<code>$ optipng -o7 file.png</code>
+-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:
+<code>$ optipng --strip all -o7 file.png</code>
