(Linux/Windows) includes mogrify which allows us to scale and convert image files in batch mode from the command line. It provides a huge number of options but you only need a few examples to start making use of it…
Creates thumbnail images using all the jpg files in the current directory:
mogrify -compress JPEG -quality 80 +profile *.jpg
Re-size all the jpg files in the current directory:
mogrify -sample 800x1200 *.jpg
Create a PDF document using all the jpg files in the current directory:
convert *jpg allinone.pdf
Convert all tif images to jpgs:
<span>mogrify -format jpg -quality 50 *.tif</span>
Scale all jpgs in the current directory by 50%:
mogrify -scale 50% *.jpg
If you need further examples, just search Google!
