Unless you need perfect quality of your screenshots, you don’t really need them to be save in PNG format.
I love saving screenshots in JPG file due to the smaller file size. A PNG screenshot weighs in at 3MB, versus one in JPG format which is only at 0.85MB. That’s a saving of more tahn 70%! A smaller file size makes it easier to send it across via email, chat and web!
Here’s how to save screenshots in JPG format on your Mac:
- Launch Terminal
defaults write com.apple.screencapture type jpg
Voila! Give it a try!
