how to use

important

always do backup before using this tool and test only on test files/folders especially made for this. understand that this tool is processing all files in subfolders. it could convert/reduce the visual quality of your files and overwrite them without any backup or warning

auto

example:

Optimize/Convert (lossless or lossy) all PNG/JPG in myfolder directory + subdirectories (auto profile) 
pingo myfolder

lossless

examples:

Optimize all PNG in current directory (fast profile) 
pingo -s0 *.png
Optimize all PNG/JPG in current directory (normal profile) 
pingo -s1 *.png *.jpg
Optimize all PNG/JPG in myfolder directory + subdirectories (good profile) 
pingo -s2 myfolder
Optimize all PNG/JPG in c:\test + subdirectories (intense profile) 
pingo -s3 c:\test
Optimize all PNG/JPG in \\server\backup + subdirectories (high profile) 
pingo -s4 \\server\backup

lossy

examples:

Convert all PNG/JPG in current directory (soft profile) 
pingo -x0 *.png *.jpg
Convert all PNG/JPG in myfolder directory + subdirectories (average profile) 
pingo -x1 myfolder

lossy combinations

examples:

Convert all PNG/JPG in current directory (average+good profile) 
pingo -x1 -s2 *.png *.jpg
Convert all PNG/JPG in myfolder directory + subdirectories (strong+intense profile) 
pingo -x2 -s3 myfolder
Convert all PNG/JPG in c:\test + subdirectories (xtreme+high profile) 
pingo -x3 -s4 c:\test
