Thanks!
Irfanview sounded familiar. Turns out I already had it installed. It only
took a few minutes to figure out how to batch reset the DPI's in my files.
Funny that it always compresses the files to about only 27% of the
original
size.

I would prefer that it left the file quality alone.

I'm only resetting the DPI numbers. I experimented with resetting to 3
different DPI's: from the original 72 DPI, to 96, 300, and 600. The
resulting new files are all exactly the same NEW size regardless of which
of
those 3 DPI's I reset the files to.

Am I just unaware that I chose some compression unintentionally?

Couldn't find anything about compression or image quality/resolution in
the
help file.
