You can use a for loop, with a little trickery to modify the name, eg 
(untested)

for i in *.jpeg; do
  name=${i%.jpeg}
  convert -resize WxH ${i} ${name}_resized.jpeg
done

if you don't want to keep the original images, then it's simpler:

for i in *.jpeg; do
  convert -resize WxH ${i} ${i}.resized
  mv ${i}.resized ${i}     # caution: overwrites original file
done
