how to use

auto optimizer

if you do not provide any options, pingo will optimize your files for Web automatically. it could do conversion (PNG to JPG), and/or picks lossy or lossless. regardless of which option you set, pingo overwrites your files without any notifications or backup if it can reduce the filesize.

there is no way to reverse the lossy process so only use pingo on test files

:: optimize all PNG for Web (lossy or lossless)
pingo *.png
:: optimize all PNG/JPG for Web (lossy or lossless) inside myfolder and subfolders
pingo myfolder


some examples and path support

:: optimize image.png with lossless fast profile
pingo -s0 image.png
:: optimize all PNG with lossless good profile
pingo -s1 *.png
:: optimize all PNG/JPG losslessly inside myfolder and subfolders
pingo -s2myfolder 
pingo -s3 c:\myfolder
pingo -s4 \\server\myfolder
