How Do I Make a Screenshot a JPG on Mac?

By default, all screenshots on the Mac are saved in PNG format.

PNG files crisp and clear but are too huge for websites and blogs.

There is a way to convert them to JPG formats with smaller file size.

Just open the image, then export it as JPG.

Is there a faster way?

Can we just do a screenshot straight into JPG?

YES!

Here’s how…

  1. Open Terminal
  2. Type in – defaults write com.apple.screencapture type jpg; killall SystemUIServer
  3. Press Return

Now all screenshots are in lightweight JPG formats.

By the way, my favourite screenshot keyboard shortcut is Shift-Command-4.
