Batch Resize Image Script

May 11, 2005

This simple script will go through all *.JPG files in the current directory and re-size them to 640x480.

for file in *.JPG
	echo "Resizing file $file ..."
	convert -resize 640x480 "$file" "$file"

If you don't have convert installed, install it with:

sudo apt-get install imagemagick

Great. Nice and easy. Thanks. I added quotes to fix spaces in filenames: convert -resize 640x480 "$file" "$file"

Never knew convert command existed. I have LOTS of images to be reduced in size. Thanks cause you lead me to the convert.
