Just in case you haven't found it:
I'm not sure if you'll have the same menu system, but on mine I always use the professional mode.
At the bottom, you'll find a small button as part of the SCAN button. That gives FILE SAVE SETTINGS.
It's odd, but in there, they put another sub menu in JPEG OPTIONS. That's where they put the compression level.
I have to confess that I save most stuff in JPEG, but archive at typically 1.2m file size for small photos. I then use
freebie Fast Stone Photo Resizer for a quick change to e-mail or Pprune sizes. I think about 170k file size fits a Pprune screen just about spot on. But don't quote me on that.
It's very fast, and you can do a whole batch at a time...changing by a RATIO or to specific sizes etc..
Just one of the goodies recommended by this forum.
