No, only for png files you can use:

Dim folders As List ' NEW
folders.Initialize
folders.Add(File.DirApp & "/www/" & ABMShared.AppName & "/images")   
ABM.ActivatePNGOptimize("DONATORKEY", folders, False , 9, False, True )

I haven't found a good library to do the same in java yet for jpg.

thanks for your reply so quickly!
users often use mobile phone to take picture and upload. so if we can change the quality of jpg, the users will feel more convenient.

many developers use canvas to change the quality of image. abm can do it?
