if you're happy with IrfanView why not use its command line options?

see i_options.txt for all its cmd line parms; I guess option /jpgq should do what you want ...

Example for /jpgq:
i_view32.exe c:\test.jpg /jpgq=75 /convert=c:\new.jpg
=> Open 'c:\test.jpg' and save it as c:\new.jpg, quality = 75
Quality range: 1 - 100.

best regards, andreas
