How to Change the Default Screenshot File Format in macOS

The default file format for macOS screenshots is .PNG, but that may wind up being more of a nuisance than you'd prefer. That's why I set my MacBook to take screenshots as JPGs, as those are better for our websites.

Here's how to change the default format for your Mac screenshots:

1. Hit Command+Space to open Spotlight.

2. Type "terminal" and select Terminal.

3. Ignoring the quotation marks, type "defaults write type " followed by the desired file format. Your options are JPG, TIFF, GIF, PDF and PNG. Make sure to enter a space between 'location' and the format.

4. Click Enter.

Now, your screenshots will appear in this format. If they do not, restart your mac and they will.
