Batch Convert JPG to PNG on Arch Linux
Mogrify is another ImageMagick command. It can do all sorts of things to an image. One of those things is converting between formats. Unless you are using the format flag, the original will be overwritten. This command has saved me HOURS of work.
You can convert all jpg files to png like this:
mogrify -format png *.jpg
You can also convert all png files to jpg like this:
mogrify -format jpg *.png

ImageMagick Installation on Arch Linux
ImageMagick is a powerful, cross platform image processing tool. It allows you to do just about anything you could want to an image from the command line. It is an extremely powerful tool that can save you hours of work.
There is a good chance that you don’t already have ImageMagick installed. If this is the case you have little to worry about. You can install it with pacman.
