Use this command to convert your batch of images under a folder

   mogrify -path imagepath  -strip -quality 50% *.jpg

this renames the files too, which means it does not preserve image name.

To specify a maximum file size, mogrify -define jpeg:extent=300kb *.jpg. However, this can be much slower than just -quality 50% and/or -resize 50%. https://stackoverflow.com/a/11920384/2097284
