Batch convert image files with ImageMagick
I recently had a number of SVG images that needed to be converted to PNG. There are a few applications that are capable of converting (Gimp, Photoshop, etc). However I wanted something simple that could batch convert them. Little did I know I already had it installed. The application is called ImageMagick.
mogrify -format png *.svg
There are an incredible number of options available. Head on over to the ImageMagick site for more details.
