Macbook OSX: Change the default image type of your screenshots from PNG to JPEG, GIF or PDF

There are a few things that I tweak when I get a new Macbook, one of which is the screenshot format (mainly because it doesnt natively render in Whatsapp). So I thought I would share the code snippet that you can run in Terminal to alter the default image type of your screenshots:

For JPEG use:

$ defaults write com.apple.screencapture type JPG

For GIF use:

$ defaults write com.apple.screencapture type GIF

For PDF use:

$ defaults write com.apple.screencapture type PDF

For PNG use:

$ defaults write com.apple.screencapture type PNG
