Remember how easy it is to screen capture on a Mac?
Cmd + Shift + 3
to take a picture of your Entire active screen.
cmd + Shift + 4
gives you some crosshairs that allow you to select what you want to copy.
Only problem is, the files are always saved as .png files. This is annoying if you want them in another format like .jpg. Normally you’d have to open your image editor of choice and then re-save it.
Turns out there is an easier way though!
All you have to do is run this Terminal Command
defaults write com.apple.screencapture type jpg
then restart your computer. Now every time you take a screenshot it will be in .jpg format.
If you want your screenshots in other formats like gif, png, or even pdf just change it in the terminal.
