How To: Take A Screenshot And Change The Screenshot’s Default Filetype With Your Mac Computer

On November 20, 2011, by Jaden

I recently purchased a Mac computer, and thus I am going to be making the switch from the Windows OS (operating system) to the Mac OS. As I am completely new to the Mac OS X operating system, one of the first things that I wondered how to do, when I was writing an article, was how do you take a screenshot on the a Mac computer? I finally stumbled upon the answer after Googling the topic, and I was very impressed on just how many different screenshot taking options there were!

I decided I would not be the only person wondering how to take screenshots on the Mac OS X operating system, so I decided I would write a quick How To guide. In this How To guide you will learn how to take screenshots on the Mac OS X operating system, and even change the file type of your screenshots.

Take Screenshots On Mac OS X

The below commands will allow you to take screenshots on your Mac OS X computer.

  • Command-Shift-3: Take a screenshot of the screen, and save it as a file on the desktop.
  • Command-Shift-4: then select an area: Take a screenshot of an area and save it as a file on the desktop.
  • Command-Shift-4-Spacebar (click a window): Take a screenshot of a window and save it as a file on the desktop.

Change Screenshots Format On Mac

If you would like to change the format of your screenshots from .png to a format of your choice such as .jpg you will need to do the following:
Step 1) – Launch Terminal by going into Finder > Applications > Utilities.
Step 2) – Enter the following command into Terminal:

defaults write com.apple.screencapture type image_format

Note: You will need to replace image_format with an image type such as: pg, tiff, pdf, png, bmp (etc).

Step 3) - After entering the command above you will need to enter one last command:

killall SystemUIServer

If everything was done correctly your screenshots should now save as the image format you specified.
