Batch convert images from the command line
A simple way to convert images in Linux is by using the command line:
convert image.jpg newImage.gif
will convert the JPG file to a GIF file.
convert -quality 78% file.jpg
will set the quality of the JPEG file to 78%
convert -resize 800×600 file.jpg
will resize the image.
Alternatively, if you wish to use a GUI tool, try Phatch.
Er, these are some nice, well-known convert (from ImageMagick) commands, but what has it do with *batch* conversion? Where’s the batch?
I have created a shell script that makes the process of batch image conversion.
