optipng

PNG image file optimization utility.

• Compress a PNG with default settings:

optipng {{file.png}}

• Compress a PNG as optimally (but slowly) as possible:

optipng -o{{7}} {{file.png}}

• Compress a PNG as quickly (but non-optimally) as possible:

optipng -o{{0}} {{file.png}}

• Compress a PNG and add interlacing:

optipng -i {{1}} {{file.png}}

• Compress a PNG and remove all metadata:

optipng -strip all {{file.png}}
