program to downgrade image (jpg) quality
 

is there such program which will downgrade the quality of an image but will leave it's dimantions as is (where you can load 100+ at the same time and it will overwrite images to lower quality) ? similar to photoshop after you save it you will be asked if you want quality from 0 - 10 but the problem is you can't load 100 images and let it do automatically in photoshop. The point of it all to have smaller sized files, let me know what program can do this. Thanks.

photoshop can
"batch process"

where is that batch process ?

help me out, what do I put for action ? save as pdf ?

usually this works for me:
open a picture, save as, pick the quality # you want to use in the batch process... this should save the number into memory.

go to file/automate/batch
source = folder - pick the input directory
destinatin = folder - pick the output directory - choose file naming you want
