ImageMagick convert to scale jpgs

Instead of using my scanner, I put my cell phone on some kind of stand, and shot a lot of paper documents (voice activation is a blessing). But then the files are unnecessarily large. Don’t need all that resolution. So

$ for i in * ; do convert "$i" -scale '33%' -quality 75 "smaller/scan_$i" ; done

And the files are 100-200k each with enough resolution to see the fine print.
